Quantum error correction beyond qubits
Takao Aoki, Go Takahashi, Tadashi Kajiya +4
Quantum computation and communication rely on the ability to manipulate quantum states robustly and with high fidelity. Thus, some form of error correction is needed to protect fra…
Demonstration of a quantum nondemolition sum gate
Jun-ichi Yoshikawa, Yoshichika Miwa, Alexander Huck +3
The sum gate is the canonical two-mode gate for universal quantum computation based on continuous quantum variables. It represents the natural analogue to a qubit C-NOT gate. In ad…
Generation of large-amplitude coherent-state superposition via ancilla-assisted photon-subtraction
Hiroki Takahashi, Kentaro Wakui, Shigenari Suzuki +4
We propose and demonstrate a novel method to generate a large-amplitude coherent-state superposition (CSS) via ancilla-assisted photon-subtraction. The ancillary mode induces quant…
