Noncyclic geometric phase in three-level Ramsey interferometry for enhanced metrology
Zhifan Zhou, Yaxin Li
In a standard two-level Ramsey interferometer, the accumulated signal phase is linearly mapped to the readout phase. Here, we introduce three-level Ramsey interferometry, in which…
Generation of hypercubic cluster states in 1-4 dimensions in a simple optical system
Zhifan Zhou, Luís E. E. de Araujo, Matt Dimario +6
Entangled graph states can be used for quantum sensing and computing applications. Error correction in measurement-based quantum computing schemes will require the construction of…
Color-switching in an optical parametric oscillator using a phase-conjugate mirror
B. E. Anderson, J. Zhao, Z. Zhou +3
We construct a phase-conjugate resonator which passively produces stable pulses that alternate between the probe and the conjugate colors. The requisite phase-conjugate mirror insi…
Geometric phase amplification in a clock interferometer for enhanced metrology
Zhifan Zhou, Sebastian C. Carrasco, Christian Sanner +2
High-precision measurements are crucial for testing the fundamental laws of nature and for advancing the technological frontier. Clock interferometry, where particles with an inter…
Properties of Two-Mode Quadrature Squeezing from Four-wave Mixing in Rubidium Vapor
LuÍs E. E. De Araujo, Zhifan Zhou, Matt Dimario +4
We present a study of homodyne measurements of two-mode, vacuum-seeded, quadrature-squeezed light generated by four-wave mixing in warm rubidium vapor. Our results reveal that the…
Nonlocal phase modulation of multimode, continuous-variable twin beams
Zhifan Zhou, Luıs E. E. de Araujo, Matt DiMario +4
We investigate experimentally the nonlocal phase modulation of multiple-frequency-mode, continuous-variable entangled twin beams. We use a pair of electro-optical phase modulators…
Quantum Test of the Local Position Invariance with Internal Clock Interferometry
Zhifan Zhou
Current attempts to test local position invariance (LPI) compare different clock transition rates with classically exchanged signals. We propose an experimental scheme for the quan…
Observation of Anomalous Moiré Patterns
Omer Amit, Or Dobkowski, Zhifan Zhou +6
Moiré patterns are omnipresent. They are important for any overlapping periodic phenomenon, from vibrational and electromagnetic, to condensed matter. Here we show, both theoretica…
Realization of a complete Stern-Gerlach interferometer: Towards a test of quantum gravity
Yair Margalit, Or Dobkowski, Zhifan Zhou +8
The Stern-Gerlach effect, discovered a century ago, has become a paradigm of quantum mechanics. Surprisingly there has been little evidence that the original scheme with freely pro…
Stern-Gerlach Interferometry with the Atom Chip
Mark Keil, Shimon Machluf, Yair Margalit +12
In this invited review in honor of 100 years since the Stern-Gerlach (SG) experiments, we describe a decade of SG interferometry on the atom chip. The SG effect has been a paradigm…
An experimental test of the geodesic rule proposition for the non-cyclic geometric phase
Zhifan Zhou, Yair Margalit, Samuel Moukouri +2
The geometric phase due to the evolution of the Hamiltonian is a central concept in quantum physics, and may become advantageous for quantum technology. In non-cyclic evolutions, a…
Realization of a complete Stern-Gerlach interferometer
Yair Margalit, Zhifan Zhou, Or Dobkowski +4
The Stern-Gerlach (SG) effect, discovered almost a century ago, has become a paradigm of quantum mechanics. Surprisingly there is little evidence that the original scheme with free…
Quantum complementarity of clocks in the context of general relativity
Zhifan Zhou, Yair Margalit, Daniel Rohrlich +2
Clocks play a special role at the interface of general relativity and quantum mechanics. We analyze a clock-interferometry thought experiment and go on to theoretically derive and…
Characterizing micro-macro transitions with an atomic-vapor-based linear optical amplifier
Zhifan Zhou, Ulrich Vogl, Ryan T. Glasser +4
Fundamentally, the dynamics of micro-macro transitions is instrumental to understanding the process of quantum-to-classical transitions; technologically, it can also facilitate the…
A self-interfering clock as a "which path" witness
Yair Margalit, Zhifan Zhou, Shimon Machluf +3
We experimentally demonstrate a new interferometry paradigm: a self-interfering clock. We split a clock into two spatially separated wave packets, and observe an interference patte…
Imaging using quantum noise properties of light
Jeremy B. Clark, Zhifan Zhou, Quentin Glorieux +2
We show that it is possible to estimate the shape of an object by measuring only the fluctuations of a probing field, allowing us to expose the object to a minimal light intensity.…
Temporally multiplexed storage of images in a Gradient Echo Memory
Quentin Glorieux, Jeremy B. Clark, Alberto M. Marino +2
We study the storage and retrieval of images in a hot atomic vapor using the gradient echo memory protocol. We demonstrate that this technique allows for the storage of multiple sp…
