Coherence protection of a silicon hole spin qubit with phase-modulated microwave driving

Sayyid I. Ibad, Yusuke Sato, Takuma Kuno +8

Hole spins in silicon quantum dots are a promising platform for quantum computing due to their strong intrinsic spin-orbit coupling (SOC), which enables fast, all-electrical contro…

Valley enhanced Rabi frequency in n-type planar Silicon-MOS quantum dot

Xunyao Luo, Xander Peetroons, Tsung-Yeh Yang +27

Electron spin resonance spectroscopy (ESR) of a single electron in planar Si-MOS quantum dot is reported in the vicinity of a valley level anti-crossing. A number of one and two-ph…

Concatenated continuous driving of silicon qubit by amplitude and phase modulation

Takuma Kuno, Takeru Utsugi, Andrew J. Ramsay +22

The rate of coherence loss is lower for a qubit under the Rabi drive than a freely evolving qubit . Building on this principle, concatenated continuous d…

Thermal circuit model for silicon quantum-dot array structures

Takeru Utsugi, Nobuhiro Kusuno, Takuma Kuno +7

Temperature rise of qubits due to heating is a critical issue in large-scale quantum computers based on quantum-dot (QD) arrays. This leads to shorter coherence times, induced read…

Single electron routing in a silicon quantum-dot array

Takeru Utsugi, Takuma Kuno, Noriyuki Lee +5

The ability to transport single electrons on a quantum dot array dramatically increases the freedom in designing quantum computation schemes that can be implemented on solid-state…

Electron Charge Sensor with Hole Current Operating at Cryogenic Temperature

Digh Hisamoto, Noriyuki Lee, Ryuta Tsuchiya +4

When SOI-PMOS functions like a capacitor-less 1T-DRAM cell, it is possible for the number of electrons to be sensed at cryogenic temperatures (5K). We developed a structure that co…
