Inferring charge-noise source locations from correlations in spin qubits
Juan S. Rojas-Arias, Akito Noiri, Jun Yoneda +7
We investigate low-frequency noise in a spin-qubit device made in isotopically purified Si/Si-Ge. Observing sizable cross-correlations among energy fluctuations of different qubits…
The origins of noise in the Zeeman splitting of spin qubits in natural-silicon devices
Juan S. Rojas-Arias, Yohei Kojima, Kenta Takeda +7
We measure and analyze noise-induced energy-fluctuations of spin qubits defined in quantum dots made of isotopically natural silicon. Combining Ramsey, time-correlation of single-s…
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…
Visual explanations of machine learning model estimating charge states in quantum dots
Yui Muto, Takumi Nakaso, Motoya Shinozaki +13
Charge state recognition in quantum dot devices is important in the preparation of quantum bits for quantum information processing. Toward auto-tuning of larger-scale quantum devic…
Feedback-based active reset of a spin qubit in silicon
Takashi Kobayashi, Takashi Nakajima, Kenta Takeda +3
Feedback control of qubits is a highly demanded technique for advanced quantum information protocols such as quantum error correction. Here we demonstrate active reset of a silicon…
Control of dephasing in spin qubits during coherent transport in silicon
MengKe Feng, Jun Yoneda, Wister Huang +12
One of the key pathways towards scalability of spin-based quantum computing systems lies in achieving long-range interactions between electrons and increasing their inter-connectiv…
