Gate reflectometry in dense quantum dot arrays [PDF]

New Journal of Physics, 2023
Abstract 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.

Remote capacitive sensing in two-dimension quantum-dot arrays [PDF]

, 2020
We investigate gate-defined quantum dots in silicon on insulator nanowire field-effect transistors fabricated using a foundry-compatible fully-depleted silicon-on-insulator (FD-SOI) process.

Three-dimensional neuroelectronic interface for peripheral nerve stimulation and recording: realization steps and contacting technology [PDF]

, 1994
A three-dimensional array of microelectrodes for use in intraneural stimulation and recording is presented. The 128 electrodes are at the tips of silicon needles, which are electrically insulated from each other.

Efficient Computations of Encodings for Quantum Error Correction

, 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.

Random background charges and Coulomb blockade in one-dimensional tunnel junction arrays

, 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.

Aharonov-Bohm phase as quantum gate in two-electron charge qubits

, 2004
We analyze the singlet-triplet splitting on a planar array of quantum dots coupled capacitively to a set of external voltage gates. The system is modelled using an extended Hubbard Hamiltonian keeping two excess electrons on the array.

Multiparticle entanglement with quantum logic networks: Application to cold trapped ions [PDF]

, 2001
We show how to construct a multi-qubit control gate on a quantum register of an arbitrary size N. This gate performs a single-qubit operation on a specific qubit conditioned by the state of other N-1 qubits.

Arrays of Josephson junctions in an environment with vanishing impedance

, 2000
The Hamiltonian operator for an unbiased array of Josephson junctions with gate voltages is constructed when only Cooper pair tunnelling and charging effects are taken into account.
