Smooth velocity shuttling for suppressing valley excitations in disordered Si/SiGe quantum dots
Ryo Nagai, Takashi Takemoto, Hiroyuki Mizuno
Coherent electron shuttling is a key requirement for realizing scalable silicon quantum computing architectures. However, in silicon qubits, the existence of nearly degenerate cond…

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…

Generating Shuttling Procedures for Constrained Silicon Quantum Dot Array
Naoto Sato, Tomonori Sekiguchi, Takeru Utsugi +1
In silicon quantum computers, a single electron is trapped in a microstructure called a quantum dot, and its spin is used as a qubit. For large-scale integration of qubits, we prev…
