Revisiting Thermal Scalability for Large-Scale Superconducting Quantum Systems
Shaswot Shresthamali, Ilkwon Byun, Teruo Tanimoto +4
The readout amplification chain imposes a critical thermal scalability bottleneck in large-scale superconducting quantum systems. This happens through three mechanisms: amplifier d…
Demonstration of microwave single-shot quantum key distribution
F. Fesquet, F. Kronowetter, M. Renger +7
Security of modern classical data encryption often relies on computationally hard problems, which can be trivialized with the advent of quantum computers. A potential remedy for th…
Microwave characterization of tantalum superconducting resonators on silicon substrate with niobium buffer layer
Yoshiro Urade, Kay Yakushiji, Manabu Tsujimoto +4
Tantalum thin films sputtered on unheated silicon substrates are characterized with microwaves at around 10 GHz in a 10 mK environment. We show that the phase of tantalum with a bo…
Quantum microwave parametric interferometer
F. Kronowetter, F. Fesquet, M. Renger +7
Classical interferometers are indispensable tools for the precise determination of various physical quantities. Their accuracy is bound by the standard quantum limit. This limit ca…
Demonstration of deterministic SWAP gate between superconducting and frequency-encoded microwave-photon qubits
Kazuki Koshino, Kunihiro Inomata
The number of superconducting qubits contained in a single quantum processor is increasing steadily. However, to realize a truly useful quantum computer, it is inevitable to increa…
Flow of quantum correlations in noisy two-mode squeezed microwave states
M. Renger, S. Pogorzalek, F. Fesquet +10
We study nonclassical correlations in propagating two-mode squeezed microwave states in the presence of noise. We focus on two different types of correlations, namely, quantum enta…
