Quantifying the effect of gate errors on variational quantum eigensolvers for quantum chemistry [PDF]
npj Quantum Information, 2022 Variational quantum eigensolvers (VQEs) are leading candidates to demonstrate near-term quantum advantage. Here, we conduct density-matrix simulations of leading gate-based VQEs for a range of molecules.

Learning quantum states and unitaries of bounded gate complexity [PDF]
PRX Quantum, 2023 While quantum state tomography is notoriously hard, most states hold little interest to practically minded tomographers. Given that states and unitaries appearing in nature are of bounded gate complexity, it is natural to ask if efficient learning ...

Adaptive Problem Solving Dynamics in Gate-Model Quantum Computers
Entropy, 2022 Gate-model quantum computer architectures represent an implementable model used to realize quantum computations. The mathematical description of the dynamical attributes of adaptive problem solving and iterative objective function evaluation in a gate ...

Pulse based Variational Quantum Optimal Control for hybrid quantum computing [PDF]
Quantum, 2023 This work studies pulse based variational quantum algorithms (VQAs), which are designed to determine the ground state of a quantum mechanical system by combining classical and quantum hardware. In contrast to more standard gate based methods, pulse based

A quantum-logic gate between distant quantum-network modules [PDF]
Science, 2021 Quantum gating at a distance The processing of quantum information is reliant on the encoding and manipulation of quantum states of a qubit. Superconducting circuits are the most advanced platform at present, but there is an issue with cross-talk between

Quantum Logic Gates Based on DNAtronics, RNAtronics, and Proteintronics
Advanced Intelligent Systems, 2021 Quantum computers (QCs) adopt an n‐state quantum mechanical system to manipulate the superposition state. However, molecular transistors are not used to build up the quantum logic gate.

Efficient quantum gate teleportation in higher dimensions [PDF]
Proceedings of the Royal Society A, 2020 The Clifford hierarchy is a nested sequence of sets of quantum gates critical to achieving fault-tolerant quantum computation. Diagonal gates of the Clifford hierarchy and ‘nearly diagonal’ semi-Clifford gates are particularly important: they admit ...
