The field of machine learning on quantum computers got a boost from new research removing a potential roadblock to the practical implementation of quantum neural networks. While theorists had previously believed an exponentially large training […]
Race Not Over Between Classical and Quantum Computers
In the race to achieve the coveted “advantage” of a quantum computer, those developing quantum algorithms are pitted against each other and against those working on classical algorithms. With each potential claim of such an […]
Rigetti and Zapata Collaboration on Compilation Stack
Rigetti and Zapata Computing announced a new phase in their long-standing partnership: the companies are developing an industry-first compilation toolchain explicitly designed for hybrid quantum-classical algorithms. As part of the work, Zapata will integrate Orquestra, […]
Quantinuum Model H1 beats classical system at game
Nonlocal games are extensions of Bell inequalities, aimed at demonstrating quantum advantage. These games are well suited for noisy quantum computers because they only require the preparation of a shallow circuit, followed by the measurement […]
Supercomputer and quantum simulations solve a difficult problem of materials science
Understanding the structural properties of molecules found in nature or synthesized in the laboratory has always been the bread and butter of materials scientists. These researchers rely upon sophisticated simulation techniques that incorporate the rules […]
Simulating Effective QED on Quantum Computers
In recent years simulations of chemistry and condensed materials has emerged as one of the preeminent applications of quantum computing, offering an exponential speedup for the solution of the electronic structure for certain strongly correlated […]
Efficient quantum programming using EASE gates on a trapped-ion quantum computer
Trapped-ion quantum computers are capable of exotic operations which entangle several qubits at once. One such powerful operation is the Efficient, Arbitrary, Simultaneously Entangling (EASE) gate. The researchers showed that EASE gates make it drastically […]
A Generalized Quantum Inner Product and Applications to Financial Engineering
A team at Wells Fargo and University of California has just released a paper on solving a central and difficult problem in Financial Engineering: Computing Weighted Sums. Those familiar with expected values, value at risk, or […]
Twist, a new language for Quantum Computing
Scientists from MIT‘s Computer Science and Artificial Intelligence (CSAIL) created their own programming language for Quantum Computing called Twist. Twist can describe and verify which pieces of data are entangled in a quantum program, through […]
