Programmable and scalable radio-frequency pulse sequence generator for multi-qubit quantum information experiments [PDF]

open access: yesarXiv, 2017
We present a versatile rf pulse control system that has been designed for multi-qubit quantum experiments. One instrument can be scaled to provide 32 channels of rf between 10 - 450 MHz. Synchronization can be achieved across multiple instruments. By using direct digital synthesis and custom control circuitry contained within a field-programmable gate ...

Mechanical Resonant Sensing of Spin Texture Dynamics in a 2D Antiferromagnet

open access: yesAdvanced Materials, EarlyView.
Detection of antiferromagnetic spin texture in a 2D magnetic crystal is achieved through nanomechanical resonators at radio frequencies. Sharp magnetic transitions that lead to abrupt changes in mechanical linear and nonlinear responses are assigned to antiferromagnetic domain motions.
