It’s not every day that a single announcement sends an entire group of stocks surging by double digits. But that’s exactly what happened yesterday when a little-known quantum computing company revealed a stunning breakthrough that shocked the market. The company – D-Wave Quantum Inc. (QBTS) – released a statement saying that one of its quantum computers completed a complex materials-science simulation in just 20 minutes……Continue reading….

Quantum computing stocks such as IonQ and Rigetti Computing have skyrocketed in recent months. Quantum computing remains a fairly speculative market. If you want exposure to quantum computing, a passive exchange-traded fund (ETF) may be the better solution.Valuation metrics show that QuantumScape Corporation may be fairly valued. Its Value Score of C indicates it would be a neutral pick for value investors.

The financial health and growth prospects of QS, demonstrate its potential to perform inline with the market. It currently has a Growth Score of D. It will become a fundamental tool for scientific research, making it easier to solve problems that were previously impossible. Researchers are making continuous progress in increasing the coherence times of qubits, reducing error rates, and developing new quantum algorithms.

The exchange between Musk and Pichai quickly evolved into a fascinating discussion about the future of quantum technology and humanity’s energy needs. When Pichai suggested the possibility of building a “quantum cluster in space” using Musk’s Starship, Musk replied, “That will probably happen.”IBM is pushing the field of quantum computing forward with Condor, the world’s largest quantum chip, and Heron, the company’s best-performing quantum chip to date.

Quantum computing 101: Classical computers use binary digits, or “bits,” to process and store data. These are just a few of the possibilities that may be enabled by quantum computing, which harnesses the laws of physics to perform calculations much faster than even the most powerful traditional computers. They all hinge on research here in the United States, the world’s undisputed leader in quantum computing.

(NYSE:IONQ) is a compelling pure-play investment, that is well-placed to capitalize on quantum computing’s rapid growth. This growth is driven by the increasing inadequacy of classical computing for solving complex problems . Quantum Processing Units (QPUs) implement a new model of computing with potential impact across industries. Turning QPUs into useful quantum computers means integrating them with state-of-the-art AI supercomputers. 

NVIDIA is working with QPU developers to build such useful, accelerated quantum supercomputers. Every year, the tech giant spends close to $1 billion in research and development in emerging tech, including quantum computing and AI. This strategy has proved fruitful, with the company holding over 3,000 patents in these domains. Microsoft has also heavily invested in the quantum programming ecosystem. Since the short-term average is above the long-term average there is a general buy signal in the stock giving a positive forecast for the stock.

On further gains, the stock will meet resistance from the short-term Moving Average at approximately $56.08. You can profit from that growth by investing in the startups or Big Tech firms building quantum computers, or by investing in firms that manufacture the components. Alternatively, you could invest in sectors set to benefit from the advent of quantum computing, like Big Data, biotech, and cybersecurity.

Gates, who is a backer of electric vehicle battery maker QuantumScape, added that he was going to try to stay involved in the “higher quality” SPACs. QuantumScape and Evolv Technology are two Gates-backed companies that have taken the SPAC path recently. QuantumScape has a consensus rating of Hold which is based on 1 buy ratings, 4 hold ratings and 1 sell ratings.

The average price target for QuantumScape is $6.46. This is based on 6 Wall Streets Analysts 12-month price targets, issued in the past 3 months. Quantum computing can potentially enhance AI’s capabilities by removing the limitations of data size, complexity, and the speed of problem solving.” Researchers are already working on enhancing current AI methods in research by applying quantum computing methods to protein structure prediction.

What Is Entropy? A Measure of Just How Little We Really Know

Kristina Armitage/Quanta Magazine

Life is an anthology of destruction. Everything you build eventually breaks. Everyone you love will die. Any sense of order or stability inevitably crumbles. The entire universe follows a dismal trek toward a dull state of ultimate turmoil. To keep track of this cosmic decay, physicists employ a concept called entropy. Entropy is a measure of disorderliness, and the declaration that entropy is always on the rise known as the second law of thermodynamics  is among nature’s most inescapable commandments……Continue reading….

Critics: 

Entropy is a scientific concept that is most commonly associated with a state of disorder, randomness, or uncertainty. The term and the concept are used in diverse fields, from classical thermodynamics, where it was first recognized, to the microscopic description of nature in statistical physics, and to the principles of information theory.

It has found far-ranging applications in chemistry and physics, in biological systems and their relation to life, in cosmology, economics, sociology, weather science, climate change and information systems including the transmission of information in telecommunication. Entropy is central to the second law of thermodynamics, which states that the entropy of an isolated system left to spontaneous evolution cannot decrease with time.

As a result, isolated systems evolve toward thermodynamic equilibrium, where the entropy is highest. A consequence of the second law of thermodynamics is that certain processes are irreversible. The thermodynamic concept was referred to by Scottish scientist and engineer William Rankine in 1850 with the names thermodynamic function and heat-potential.

In 1865, German physicist Rudolf Clausius, one of the leading founders of the field of thermodynamics, defined it as the quotient of an infinitesimal amount of heat to the instantaneous temperature. He initially described it as transformation-content, in German Verwandlungsinhalt, and later coined the term entropy from a Greek word for transformation.

Austrian physicist Ludwig Boltzmann explained entropy as the measure of the number of possible microscopic arrangements or states of individual atoms and molecules of a system that comply with the macroscopic condition of the system. He thereby introduced the concept of statistical disorder and probability distributions into a new field of thermodynamics, called statistical mechanics, .

Found the link between the microscopic interactions, which fluctuate about an average configuration, to the macroscopically observable behaviour, in form of a simple logarithmic law, with a proportionality constant, the Boltzmann constant, which has become one of the defining universal constants for the modern International System of Units (SI).

The concept of entropy is described by two principal approaches, the macroscopic perspective of classical thermodynamics, and the microscopic description central to statistical mechanics. The classical approach defines entropy in terms of macroscopically measurable physical properties, such as bulk mass, volume, pressure, and temperature.

The statistical definition of entropy defines it in terms of the statistics of the motions of the microscopic constituents of a system — modelled at first classically, e.g. Newtonian particles constituting a gas, and later quantum-mechanically (photons, phonons, spins, etc.). The two approaches form a consistent, unified view of the same phenomenon as expressed in the second law of thermodynamics, which has found universal applicability to physical processes.

Many thermodynamic properties are defined by physical variables that define a state of thermodynamic equilibrium, which essentially are state variables. State variables depend only on the equilibrium condition, not on the path evolution to that state. State variables can be functions of state, also called state functions, in a sense that one state variable is a mathematical function of other state variables.

Often, if some properties of a system are determined, they are sufficient to determine the state of the system and thus other properties’ values. For example, temperature and pressure of a given quantity of gas determine its state, and thus also its volume via the ideal gas law. A system composed of a pure substance of a single phase at a particular uniform temperature and pressure is determined, and is thus a particular state, and has a particular volume.

The fact that entropy is a function of state makes it useful. In the Carnot cycle, the working fluid returns to the same state that it had at the start of the cycle, hence the change or line integral of any state function, such as entropy, over this reversible cycle is zero. Romanian American economist Nicholas Georgescu-Roegen, a progenitor in economics and a paradigm founder of ecological economics, made extensive use of the entropy concept in his magnum opus on The Entropy Law and the Economic Process. Due to Georgescu-Roegen’s work, the 

laws of thermodynamics form an integral part of the ecological economics school. Although his work was blemished somewhat by mistakes, a full chapter on the economics of Georgescu-Roegen has approvingly been included in one elementary physics textbook on the historical development of thermodynamics.

In economics, Georgescu-Roegen’s work has generated the term ‘entropy pessimism’. Since the 1990s, leading ecological economist and steady-state theorist Herman Daly – a student of Georgescu-Roegen – has been the economics profession’s most influential proponent of the entropy pessimism position.
