Suppression of Crosstalk in Quantum Circuit Based on Instruction Exchange Rules and Duration
Entropy, 2023 Crosstalk is the primary source of noise in quantum computing equipment. The parallel execution of multiple instructions in quantum computation causes crosstalk, which causes coupling between signal lines and mutual inductance and capacitance between ...

Fast Multiqubit Gates through Simultaneous Two-Qubit Gates
PRX Quantum, 2021 Near-term quantum computers are limited by the decoherence of qubits to only being able to run low-depth quantum circuits with acceptable fidelity. This severely restricts what quantum algorithms can be compiled and implemented on such devices.

Approaching the theoretical limit in quantum gate decomposition [PDF]
Quantum, 2022 In this work we propose a novel numerical approach to decompose general quantum programs in terms of single- and two-qubit quantum gates with a $CNOT$ gate count very close to the current theoretical lower bounds.

Quantum compiling with a variational instruction set for accurate and fast quantum computing
Physical Review Research, 2023 The quantum instruction set (QIS) is defined as the quantum gates that are physically realizable by controlling the qubits in quantum hardware. Compiling quantum circuits into the product of the gates in a properly defined QIS is a fundamental step in ...

Reducing CNOT count in quantum Fourier transform for the linear nearest-neighbor architecture
Scientific Reports, 2023 Physical limitations of quantum hardware often necessitate nearest-neighbor (NN) architecture. When synthesizing quantum circuits using the basic gate library, which consists of CNOT and single-qubit gates, CNOT gates are required to convert a quantum ...
