Effects of residual exchange coupling on simultaneously driven spin qubits
Heun Mo Yoo, Tanner M. Janda, Victor Yu +3
Exchange coupling and microwave drives are widely used control mechanisms for spin qubits. However, the influence of exchange coupling on microwave-driven spin dynamics is not full…
Spectroscopy of low-lying valley states in hot Si/SiGe quantum dots
Connor Nasseraddin, Heun Mo Yoo, Tanner M. Janda +1
The presence of low-lying valley states in Si may hinder the development of large-scale spin-based quantum processors. Rapid prototyping of novel Si/SiGe heterostructures and gate…
Directly visualizing the energy level structure of quantum dot molecules
Heun Mo Yoo, Tanner M. Janda, Connor Nasseraddin +1
The orbital, spin and valley degrees of freedom in silicon quantum dots support many modes of spin qubit operation. However, it is generally challenging to obtain information about…
Sign-resolved nanoscale readout and control of hidden antiferromagnetic spin order
A. Schmid, D. Siebenkotten, D. Dai +16
Antiferromagnetic memories promise ultrafast, stray-field-free information storage. Yet perfect magnetic compensation conceals the information carrier itself: the sign of the Néel…
Microwave response of electrically driven spins in a three-qubit quantum processor
Tanner M. Janda, Heun Mo Yoo, Connor Nasseraddin +3
In electric dipole spin resonance (EDSR), a single spin is electrically driven in the field gradient produced by a micromagnet. While EDSR has enabled high fidelity gate operations…
