Demonstration of a fully tuneable entangling gate for continuous-variable one-way quantum computation
Shota Yokoyama, Ryuji Ukai, Seiji C. Armstrong +3
We introduce a fully tuneable entangling gate for continuous-variable one-way quantum computation. We present a proof-of-principle demonstration by propagating two independent opti…
Nonlocal quantum gate on quantum continuous variables with minimum resources
Shota Yokoyama, Ryuji Ukai, Jun-ichi Yoshikawa +3
We experimentally demonstrate, with an all-optical setup, a nonlocal deterministic quantum non-demolition interaction gate applicable to quantum states at nodes separated by a phys…
Noise analysis of single-qumode Gaussian operations using continuous-variable cluster states
Rafael N. Alexander, Seiji C. Armstrong, Ryuji Ukai +1
We consider measurement-based quantum computation that uses scalable continuous-variable cluster states with a one-dimensional topology. The physical resource, known here as the du…
Ultra-Large-Scale Continuous-Variable Cluster States Multiplexed in the Time Domain
Shota Yokoyama, Ryuji Ukai, Seiji C. Armstrong +7
Quantum computers promise ultrafast performance of certain tasks. Experimentally appealing, measurement-based quantum computation (MBQC) requires an entangled resource called a clu…
Demonstration of a Controlled-Phase Gate for Continuous-Variable One-Way Quantum Computation
Ryuji Ukai, Shota Yokoyama, Jun-ichi Yoshikawa +2
We experimentally demonstrate a controlled-phase gate for continuous variables in a fully measurement-based fashion. In our scheme, the two independent input states of the gate, en…
Reversing Quantum Nondemolition Interaction as Quantum Erasing
Yoshichika Miwa, Jun-ichi Yoshikawa, Ryuji Ukai +2
We reverse a quantum nondemolition (QND) interaction and restore the signal quantum state by measurement and feedforward. This operation corresponds to quantum erasing for continuo…
