Addressable Quantum Gates [PDF]
ACM Transactions on Quantum Computing, 2021 We extend the circuit model of quantum computation so that the wiring between gates is soft-coded within registers inside the gates. The addresses in these registers can be manipulated and put into superpositions. This aims at capturing indefinite causal

Universal holonomic quantum gates over geometric spin qubits with polarised microwaves. [PDF]
Nat Commun, 2018 A microwave shares a nonintuitive phase called the geometric phase with an interacting electron spin after an elastic scattering. The geometric phase, generally discarded as a global phase, allows universal holonomic gating of an ideal logical qubit ...

Quantum-state preparation with universal gate decompositions [PDF]
, 2011 In quantum computation every unitary operation can be decomposed into quantum circuits-a series of single-qubit rotations and a single type entangling two-qubit gates, such as controlled-NOT (CNOT) gates.
