The General Quantum Limit for and the Optimization of the Minimum Measurable Frequency Shift in a Laser
Selim M. Shahriar, Ruoxi Zhu, Jinyang Li +1
We show that, contrary to conventional understanding, the minimum measurable frequency shift (MMFS) for a single-mode ideal laser is determined by a combination of phase diffusion…
Modified One-Axis-Twist Squeezing for Deterministic Orientation Control of Schrödinger Cat States with Unknown Atom-Number Parity
Jinyang Li, Selim M. Shahriar
The Schrödinger cat state protocol (SCSP) makes use of a Schrödinger cat (SC) state generated with one-axis-twist squeezing (OATS) to enhance the sensitivity. In principle, the S…
Impact of spontaneous emission on spin-squeezed quantum sensors
Jinyang Li, Selim M. Shahriar
The echo squeezing protocols (ESPs) are techniques that amplify the phase shift in a quantum sensor with one-axis-twist squeezing (OATS). For atomic sensors, spontaneous emission (…
Spin-squeezed vector atomic magnetometry
Jinyang Li, Gour Pati, Renu Tripathi +1
Atomic magnetometers based on Zeeman shift measurement have the potential for high sensitivity and long-term stability. Like other atomic sensors including atomic clocks and atom i…
Slow Light Augmented Unbalanced Interferometry for Extreme Enhancement in Sensitivity of Measuring Frequency Shift in a Laser
Ruoxi Zhu, Zifan Zhou, Jinyang Li +3
We demonstrate a slow-light augmented unbalanced Mach-Zehnder Interferometer (MZI) which can be used to enhance very significantly the sensitivity of measuring the frequency shift…
Sensitivity and Bandwidth of a Point-Source-Interferometry-based Inertial Measurement Unit Employing Large Momentum Transfer and Launched Atoms
Jinyang Li, Timothy Kovachy, Jason Bonacum +1
We analyze theoretically the sensitivity of accelerometry and rotation sensing with a point source interferometer employing large momentum transfer (LMT) and present a design of an…
