Controlling the Inhomogeneous Broadening and Impedance Matching of a Spin Ensemble
Mathieu Couillard, Debdip Guchait, Hiroki Takahashi +1
The authors use a magnetic field gradient generated by an anti‑Helmholtz coil to shape the spectral distribution of a spin ensemble and achieve impedance matching to a transmission…
A near-quantum-limited diamond maser amplifier operating at millikelvin temperatures
Morihiro Ohta, Ching-Ping Lee, Vincent P. M. Sietses +10
Microwave quantum technologies require amplification of weak signals with minimal added noise at millikelvin temperatures. This stringent demand has been met with superconducting p…
Stabilizing an optical cavity containing a bulk diamond crystal at millikelvin temperatures in a cryogen-free dilution refrigerator
Tatsuki Hamamoto, Amit Bhunia, Hiroki Takahashi +1
We successfully stabilized a Fabry-Pérot optical cavity incorporating a bulk diamond crystal at millikelvin temperatures in a cryogen-free dilution refrigerator with the pulse-tub…
