Multiplayer quantum games
Recently the concept of quantum information has been introduced into game theory. Here we present the first study of quantum games with more than two players. We discover that such games can possess… Expand

It is found that superposition and entanglement are sustained in this living system for at least tens of microseconds, exceeding the durations achieved in the best comparable man-made molecular systems. Expand
Quantum computational chemistry
With small quantum computers becoming a reality, first applications are eagerly sought. Quantum chemistry presents a spectrum of computational problems, from relatively easy to classically… Expand
Efficient Variational Quantum Simulator Incorporating Active Error Minimization
This work proposes a variational method involving closely integrated classical and quantum coprocessors and finds that it is efficient and appears to be fundamentally more robust against error accumulation than a more conventional optimised Trotterisation technique. Expand
Practical Quantum Error Mitigation for Near-Future Applications
This work describes a protocol for systematically measuring the effect of errors so as to design efficient QEM circuits and introduces an exponential variant of the extrapolation method to enable practical implementation of these ideas. Expand

An overview of the field of Variational Quantum Algorithms is presented and strategies to overcome their challenges as well as the exciting prospects for using them as a means to obtain quantum advantage are discussed. Expand
Theory of variational quantum simulation
This work completes the theory of variational quantum simulation of general real and imaginary time evolution and it is applicable to near-term quantum hardware. Expand

This work proposes a variational algorithm that is hybrid, suitable for error mitigation and can exploit shallow quantum circuits, and can be implemented with current quantum computers, and uses it to find the ground-state energy of many-particle systems. Expand
Topological quantum computing with a very noisy network and local error rates approaching one percent
This work describes a method by which even error-prone cells can perform purification: groups of cells generate shared resource states, which then enable stabilization of topologically encoded data. Expand
