All-microwave manipulation of superconducting qubits with a fixed-frequency transmon coupler
Shotaro Shirai, Yuta Okubo, Kohei Matsuura +3
All-microwave control of fixed-frequency superconducting quantum computing circuits is advantageous for minimizing the noise channels and wiring costs. Here we introduce a swap int…

Proposal of an eavesdropping experiment for BB84 QKD protocol with 1-3 phase-covariant quantum cloner
Yuta Okubo, Francesco Buscemi, Akihisa Tomita
We propose an eavesdropping experiment with linear optical 1-3 phase-covariant quantum cloner. In this paper, we have designed an optical circuit of the cloner and shown how the ea…
