Quantum-optimized phase closure for robust interferometric imaging
Zhenning Liu, Emil T. Khabiboulline, Lorcan O. Conlon +7
Closure phase enables imaging with ground-based interferometric arrays by canceling telescope-dependent phase errors due to atmospheric fluctuations. It can be obtained by measurin…
Eliminating photon transport in long-baseline optical interferometry using quantum memories
Yousef K. Chahine, Chaohan Cui, William DeRocco +11
In this paper, we describe the fundamental operating mechanisms of optical interferometry using quantum memory and entanglement. We show how these remove the optical delay line bot…
Fundamental Limit for One versus Two Point Sources Detection using Direct Imaging
Parth Hemant Darekar, Amit Kumar Jha, Michael R. Grace +2
We consider the task of distinguishing between a single weak incoherent optical point source and two weak incoherent optical point sources located symmetrically about the first sou…
Boosted linear-optical measurements on single-rail qubits with unentangled ancillas
Aqil Sajjad, Isack Padilla, Saikat Guha
Any quantum state of the radiation field, sliced in small non-overlapping space-time bins is a collection of single-rail qubits, each spanning the vacuum and single-photon Fock sta…
Superresolution imaging with entanglement-enhanced telescopy
Isack Padilla, Aqil Sajjad, Babak N. Saif +1
Long-baseline interferometry will be possible using pre-shared entanglement between two telescope sites to mimic the standard phase-scanning interferometer, but without physical be…
Towards quantum-enhanced long-baseline optical/near-IR interferometry
Jayadev K. Rajagopal, Ryan M. Lau, Isack Padilla +10
Microarcsecond resolutions afforded by an optical-NIR array with kilometer-baselines would enable breakthrough science. However significant technology barriers exist in transportin…
Quantum resolution limit of long-baseline imaging using distributed entanglement
Isack Padilla, Aqil Sajjad, Babak N. Saif +1
It has been shown that shared entanglement between two telescope sites can in principle be used to localize a point source by mimicking the standard phase-scanning interferometer,…
Bipartite entanglement of noisy stabilizer states through the lens of stabilizer codes
Kenneth Goodenough, Aqil Sajjad, Eneet Kaur +2
Stabilizer states are a prime resource for a number of applications in quantum information science, such as secret-sharing and measurement-based quantum computation. This motivates…
Lower bounds on bipartite entanglement in noisy graph states
Aqil Sajjad, Eneet Kaur, Kenneth Goodenough +2
Graph states are a key resource for a number of applications in quantum information theory. Due to the inherent noise in noisy intermediate-scale quantum (NISQ) era devices, it is…
Quantum limits of parameter estimation in long-baseline imaging
Aqil Sajjad, Michael R Grace, Saikat Guha
Distributed aperture telescopes are a well-established approach for boosting resolution in astronomical imaging. However, theoretical limits on quantitative imaging precision, and…
Attaining quantum limited precision of localizing an object in passive imaging
Aqil Sajjad, Michael R Grace, Quntao Zhuang +1
We investigate our ability to determine the mean position, or centroid, of a linear array of equally-bright incoherent point sources of light, whose continuum limit is the problem…
Understanding diboson anomalies
Aqil Sajjad
We conduct a model-independent effective theory analysis of hypercharged fields with various spin structures towards understanding the diboson excess found in LHC run I, as well as…
Continuum-Mediated Dark Matter-Baryon Scattering
Andrey Katz, Matthew Reece, Aqil Sajjad
Many models of dark matter scattering with baryons may be treated either as a simple contact interaction or as the exchange of a light mediator particle. We study an alternative, i…
Naturalness, b to s gamma, and SUSY Heavy Higgses
Andrey Katz, Matthew Reece, Aqil Sajjad
We explore naturalness constraints on the masses of the heavy Higgs bosons H^0, H^+/-, and A^0 in supersymmetric theories. We show that, in any extension of MSSM which accommodates…
Towards an Effective Field Theory on the Light-Shell
Howard Georgi, Greg Kestin, Aqil Sajjad
We discuss our work toward the construction of a light-shell effective theory (LSET), an effective field theory for describing the matter emerging from high-energy collisions and t…
The Photon Propagator in Light-Shell Gauge
Howard Georgi, Greg Kestin, Aqil Sajjad
We derive the photon propagator in light-shell gauge, which was first introduced in the context of light-shell effective theory.
Hunting for Dynamical Supersymmetry Breaking in Theories That S-confine
Tongyan Lin, John D. Mason, Aqil Sajjad
The s-confining theories are a class of supersymmetric gauge theories with infrared dynamics which are well-understood. Perturbing such theories can give rise to dynamical supersym…
Color Fields on the Light-Shell
Howard Georgi, Greg Kestin, Aqil Sajjad
We study the classical color radiation from very high energy collisions that produce colored particles. In the extreme high energy limit, the classical color fields are confined to…
