Crosstalk analysis for simultaneously driven two-qubit gates in spin qubit arrays [PDF]
, 2021 One of the challenges when scaling up semiconductor-based quantum processors consists in the presence of crosstalk errors caused by control operations on neighboring qubits. In previous work, crosstalk in spin qubit arrays has been investigated for non-driven single qubits near individually driven quantum gates and for two simultaneously driven single ...

Robust shaped pulses for arrays of superconducting or semiconductor spin qubits with fixed Ising coupling [PDF]
Phys. Rev. A 109, 032605 (2024), 2023 A major current challenge in solid-state quantum computing is to scale qubit arrays to a larger number of qubits. This is hampered by the complexity of the control wiring for the large number of independently tunable interqubit couplings within these arrays.

Efficient orthogonal control of tunnel couplings in a quantum dot array [PDF]
Phys. Rev. Applied 13, 054018 (2020), 2020 Electrostatically-defined semiconductor quantum dot arrays offer a promising platform for quantum computation and quantum simulation. However, crosstalk of gate voltages to dot potentials and inter-dot tunnel couplings complicates the tuning of the device parameters.

Parallelized Particle Swarm Optimization on FPGA for Realtime Ballistic Target Tracking
Sensors, 2023 This paper addresses the problem of tracking a high-speed ballistic target in real time. Particle swarm optimization (PSO) can be a solution to overcome the motion of the ballistic target and the nonlinearity of the measurement model. However, in general,

Quantum circuits with uniformly controlled one-qubit gates [PDF]
Phys. Rev. A 71, 052330 (2005), 2004 Uniformly controlled one-qubit gates are quantum gates which can be represented as direct sums of two-dimensional unitary operators acting on a single qubit. We present a quantum gate array which implements any n-qubit gate of this type using at most 2^{n-1} - 1 controlled-NOT gates, 2^{n-1} one-qubit gates and a single diagonal n-qubit gate.
