Heralded Leakage Detection with Preserved Computational-State Coherence in a Fixed-Frequency Transmon
Takeaki Miyamura, Zhiling Wang, Peter A. Spring +5
Leakage out of the computational subspace is a major error mechanism in superconducting quantum processors. Detecting leakage without disturbing the encoded quantum information can…
Deterministic Quantum Communication Between Fixed-Frequency Superconducting Qubits via Broadband Resonators
Takeaki Miyamura, Zhiling Wang, Kohei Matsuura +5
Quantum communication between remote chips is essential for realizing large-scale superconducting quantum computers. For such communication, itinerant microwave photons propagating…
Temporal-Mode Engineering for Multiplexed Microwave Photons and Mode-Selective Quantum State Transfer
Keika Sunada, Takeaki Miyamura, Kohei Matsuura +4
Quantum communication between distant superconducting qubits on separate chips using itinerant microwave photons has been studied to realize distributed quantum information process…
Generation of frequency-bin-encoded dual-rail cluster states via time-frequency multiplexing of microwave photonic qubits
Zhiling Wang, Takeaki Miyamura, Yoshiki Sunada +4
Cluster states are a class of multi-qubit entangled states with broad applications such as quantum metrology and one-way quantum computing. Here, we present a protocol to generate…
Generation of Frequency-Tunable Shaped Single Microwave Photons Using a Fixed-Frequency Superconducting Qubit
Takeaki Miyamura, Yoshiki Sunada, Zhiling Wang +3
Scaling up a superconducting quantum computer will likely require quantum communication between remote chips, which can be implemented using an itinerant microwave photon in a tran…
