Understanding Quantum Primacy And How We Got There | A quantum computer is a remarkable device. While, at current, it’s still limited in its application, we now know that it can be faster than the fastest computers we currently have access to. As Scientific American reminds us, quantum primacy (also known as quantum supremacy) is the point at which a quantum machine outstrips a classical computer. Computers have helped advance civilization and increased our ability to process data many times over. Even so, there are some problems that not even they can solve. The more answers we find, the more questions we have. Quantum computing was built to multiply computing power by tapping into what we know about quantum states. While a traditional computer is limited by bits, quantum computers aren’t, allowing them to perform calculations many times faster. Or so it’s assumed. There’s still much debate as to whether we’ve gotten to the point of quantum primacy or not. Are quantum computers faster than regular computers, or aren’t they? Source: SCIENCE 2.0.

Quantum computing enhanced machine learning for physico-chemical applications | Machine learning (ML) has emerged into formidable force for identifying hidden but pertinent patterns within a given data set with the objective of subsequent generation of automated predictive behavior. In the recent years, it is safe to conclude that ML and its close cousin deep learning (DL) have ushered unprecedented developments in all areas of physical sciences especially chemistry. Not only the classical variants of ML , even those trainable on near-term quantum hardwares have been developed with promising outcomes. Such algorithms have revolutionzed material design and performance of photo-voltaics, electronic structure calculations of ground and excited states of correlated matter, computation of force-fields and potential energy surfaces informing chemical reaction dynamics, reactivity inspired rational strategies of drug designing and even classification of phases of matter with accurate identification of emergent criticality. In this review we shall explicate a subset of such topics and delineate the contributions made by both classical and quantum computing enhanced machine learning algorithms over the past few years. We shall not only present a brief overview of the well-known techniques but also highlight their learning strategies using statistical physical insight. The objective of the review is to not only to foster exposition to the aforesaid techniques but also to empower and promote cross-pollination among future-research in all areas of chemistry which can benefit from ML and in turn can potentially accelerate the growth of such algorithms.

Technical Perspective: On Proofs, Entanglement, and Games | What is a proof? Philosophers and mathematicians have pondered this question for centuries. Theoretical computer science offers a rigorous handle on this deep question. One can think of a proof as a two-player game: an all-powerful though un-trusted prover who provides a proof of the statement, and a computationally weak verifier who needs only to verify it. In fact, NP problems can be presented exactly in this verifier-prover language. Viewing proofs as games turned out to be remarkably fruitful. For example, interactive proofs were invented, resembling Socratic dialogues; these are games in which the prover and verifier exchange (possibly randomized) messages. And, why just one prover? In multi-prover interactive proofs (MIP) several non-communicating provers are involved. This gave birth to beautiful concepts such as zero knowledge and probabilistically checkable proofs (PCPs) with immense impact not only theoretically but also in practice, for example, in digital currency.
