Rapid single-shot parity spin readout in a silicon double quantum dot with fidelity exceeding 99 %
Kenta Takeda, Akito Noiri, Takashi Nakajima +5
Silicon-based spin qubits offer a potential pathway toward realizing a scalable quantum computer owing to their compatibility with semiconductor manufacturing technologies. Recent…
Floquet systems with continuous dynamical symmetries: characterization, time-dependent Noether charge, and solvability
Yukio Kaneko, Tatsuhiko N. Ikeda
We study quantum Floquet (periodically-driven) systems having continuous dynamical symmetry (CDS) consisting of a time translation and a unitary transformation on the Hilbert space…
Dynamical nuclear spin polarization in a quantum dot with an electron spin driven by electric dipole spin resonance
Peter Stano, Takashi Nakajima, Akito Noiri +2
We analyze the polarization of nuclear spins in a quantum dot induced by a single-electron spin that is electrically driven to perform coherent Rabi oscillations. We derive the ass…
Josephson diode effect derived from short-range coherent coupling
Sadashige Matsuo, Takaya Imoto, Tomohiro Yokoyama +6
Superconducting devices with broken time-reversal and spatial-inversion symmetries can exhibit novel superconducting phenomena. The observation of superconducting diode effects, wh…
Engineering of anomalous Josephson effect in coherently coupled Josephson junctions
Sadashige Matsuo, Takaya Imoto, Tomohiro Yokoyama +6
A Josephson junction (JJ) is a key device in the development of superconducting circuits, wherein a supercurrent in the JJ is controlled by the phase difference between the two sup…
Phonon-mediated spin dynamics in a two-electron double quantum dot under a phonon temperature gradient
Kazuyuki Kuroyama, Sadashige Matsuo, Seigo Tarucha +1
We have theoretically studied phonon-mediated spin-flip processes of electrons in a GaAs double quantum dot (DQD) holding two spins, under a phonon temperature gradient over the DQ…
Blueprint for quantum computing using electrons on helium
Erika Kawakami, Jiabao Chen, Mónica Benito +1
We present a blueprint for building a fault-tolerant quantum computer using the spin states of electrons on the surface of liquid helium. We propose to use ferromagnetic micropilla…
Spatial noise correlations beyond nearest-neighbor in Si/SiGe spin qubits
Juan S. Rojas-Arias, Akito Noiri, Peter Stano +8
We detect correlations in qubit-energy fluctuations of non-neighboring qubits defined in isotopically purified Si/SiGe quantum dots. At low frequencies (where the noise is stronges…
