Shankset al.present a scanning transmon qubit, map its coupling strength to a separate resonator, and propose its use to probe photon number in a superconducting resonator lattice.

Toshiba researchers have devised a double-transmon coupler, the world's first tunable coupler that can both completely turn off coupling and operate the two qubit gates at high speed for two fixed ...

The Toshiba-RIKEN team achieved a world-class coherence time for the transmon qubit, a short gate time of 48 ns, and reduced the residual coupling strength to as low as 6 kHz, thereby achieving a ...

One of the pillars of this success was the development of the transmon qubit. The typical transmon-based toolkit consists of a coplanar waveguide (CPW) resonator for dispersive readout and capacitive ...

High-Fidelity, Frequency-Flexible Two-Qubit Fluxonium Gates with a Transmon Coupler. Physical Review X , 2023; 13 (3) DOI: 10.1103/PhysRevX.13.031035 Cite This Page : ...

Current technology can turn off the coupling of transmon qubits with close frequencies, but this is prone to crosstalk errors that occur on one of the qubits when the other qubit is irradiated ...

The team of researchers embedded the Andreev spin qubit in a superconducting transmon qubit, and found the qubits had strong coherent qubit–qubit coupling — crucial for a hybrid architecture that has ...

The Toshiba-RIKEN team achieved a world-class coherence time for the transmon qubit, a short gate time of 48 ns, and reduced the residual coupling strength to as low as 6 kHz, thereby achieving a ...

Paving the way for the realization of high-performance quantum computers that will contribute to solving various social issues TOKYO, Sept. 16, 2022 /PRNewswire/ -- Researchers at Toshiba ...

Gates must also be executed quickly and the strength of residual coupling must be suppressed to reduce the errors it causes. The Toshiba-RIKEN team achieved a world-class coherence time for the ...
