Researchers have developed an algorithm that uses the most quantum bits to date to calculate ground state energy, the lowest-energy state in a quantum mechanical system. The discovery could make it easier to design new […]
A Quantum Ensemble — a set of quantum states with their corresponding probabilities — is essential to the encoding of classical information for transmission over quantum channels. But receivers must be able to ‘guess’ the […]
A sudoku-style mathematical puzzle that is known to have no classical solution has been found to be soluble if the objects being arrayed in a square grid show quantum behavior. The problem, posed by Swiss […]
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 […]
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 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, […]
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 […]
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 […]
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 […]
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 […]
