Optimized phase sensing in a truncated SU(1,1) interferometer
Prasoon Gupta, Bonnie L. Schmittberger, Brian E. Anderson +2
Homodyne detection is often used for interferometers based on nonlinear optical gain media. For the configuration of a seeded, 'truncated SU(1,1)' interferometer Anderson et al. (P…
Improved measurement of two-mode quantum correlations using a phase-sensitive amplifier
Tian Li, Brian E. Anderson, Travis Horrom +3
We demonstrate the ability of a phase-sensitive amplifier (PSA) to pre-amplify a selected quadrature of one mode of a two-mode squeezed state in order to improve the measurement of…
Phase sensing beyond the standard quantum limit with a truncated SU(1,1) interferometer
Brian E. Anderson, Prasoon Gupta, Bonnie L. Schmittberger +4
An SU(1,1) interferometer replaces the beamsplitters in a Mach-Zehnder interferometer with nonlinear interactions and offers the potential of achieving high phase sensitivity in ap…
The effect of input phase modulation to a phase-sensitive optical amplifier
Tian Li, Brian E. Anderson, Travis Horrom +2
Many optical applications depend on amplitude modulating optical beams using devices such as acousto-optical modulators (AOMs) or optical choppers. Methods to add amplitude modulat…
Multi-channel entanglement distribution using spatial multiplexing from four-wave mixing in atomic vapor
Prasoon Gupta, Travis Horrom, Brian E. Anderson +2
Four-wave mixing in atomic vapor allows for the generation of multi-spatial-mode states of light containing many pairs of two-mode entangled vacuum beams. This in principle can be…
Accurate and robust unitary transformation of a high-dimensional quantum system
B. E. Anderson, H. Sosa-Martinez, C. A. Riofrío +2
Quantum control in large dimensional Hilbert spaces is essential for realizing the power of quantum information processing. For closed quantum systems the relevant input/output map…
Quantum state tomography by continuous measurement and compressed sensing
A. Smith, C. A. Riofrío, B. E. Anderson +3
The need to perform quantum state tomography on ever larger systems has spurred a search for methods that yield good estimates from incomplete data. We study the performance of com…
Three-Axis Measurement and Cancellation of Background Magnetic Fields to less than 50 uG in a Cold Atom Experiment
Aaron Smith, Brian E. Anderson, Souma Chaudhury +1
Many experiments involving cold and ultracold atomic gases require very precise control of magnetic fields that couple to and drive the atomic spins. Examples include quantum contr…
