Programmable quantum gate arrays [PDF]
Physical Review Letters, 1997 We show how to construct quantum gate arrays that can be programmed to perform different unitary operations on a data register, depending on the input to some program register. It is shown that a universal quantum gate array - a gate array which can be programmed to perform any unitary operation - exists only if one allows the gate array to operate in ...

Gate reflectometry in dense quantum dot arrays [PDF]
New Journal of Physics, 2023 Silicon quantum devices are maturing from academic single- and two-qubit devices to industrially-fabricated dense quantum-dot (QD) arrays, increasing operational complexity and the need for better pulsed-gate and readout techniques.

Universal gate operations on nuclear spin qubits in an optical tweezer array of $^{171}$Yb atoms [PDF]
Phys. Rev. X 12, 021028 (2022), 2021 Neutral atom arrays are a rapidly developing platform for quantum science. In this work, we demonstrate a universal set of quantum gate operations on a new type of neutral atom qubit: a nuclear spin in an alkaline earth-like atom (AEA), $^{171}$Yb.

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.

Random background charges and Coulomb blockade in one-dimensional tunnel junction arrays [PDF]
Phys. Rev. B 63, 014201 (2001), 2000 We have numerically studied the behavior of one dimensional tunnel junction arrays when random background charges are included using the ``orthodox'' theory of single electron tunneling. Random background charge distributions are verified in both amplitude and density. The use of a uniform array as a transistor is discussed both with and without random

Fast universal two-qubit gate for neutral fermionic atoms in optical tweezers [PDF]
Physical Review Research, 2021 An array of ultracold neutral atoms held in optical microtraps is a promising platform for quantum computation. One of the major bottlenecks of this platform is the weak coupling strength between adjacent atoms, which limits the speed of two-qubit gates.

Efficient Computations of Encodings for Quantum Error Correction [PDF]
, 1996 We show how, given any set of generators of the stabilizer of a quantum code, an efficient gate array that computes the codewords can be constructed. For an n-qubit code whose stabilizer has d generators, the resulting gate array consists of O(n d) operations, and converts k-qubit data (where k = n - d) into n-qubit codewords.

A Low-Power Reconfigurable Logic Array Based on Double-Gate Transistors [PDF]
, 2008 A fine-grained reconfigurable architecture based on double gate technology is proposed and analyzed. The logic function operating on the first gate of a double-gate (DG) transistor is reconfigured by altering the charge on its second gate.
