The Complexity of NISQ
Sitan Chen, Jordan Cotler, Hsin-Yuan Huang +1
The recent proliferation of NISQ devices has made it imperative to understand their computational power. In this work, we define and study the complexity class , wh…
Improved Spatial Resolution Achieved by Chromatic Intensity Interferometry
Lu-Chuan Liu, Luo-Yuan Qu, Cheng Wu +8
Interferometers are widely used in imaging technologies to achieve enhanced spatial resolution, but require that the incoming photons be indistinguishable. In previous work, we bui…
Chromatic interferometry with small frequency differences
Luo-Yuan Qu, Lu-Chuan Liu, Jordan Cotler +9
By developing a `two-crystal' method for color erasure, we can broaden the scope of chromatic interferometry to include optical photons whose frequency difference falls outside of…
Quantum Overlapping Tomography
Jordan Cotler, Frank Wilczek
It is now experimentally possible to entangle thousands of qubits, and efficiently measure each qubit in parallel in a distinct basis. To fully characterize an unknown entangled st…
Color Erasure Detectors Enable Chromatic Interferometry
Luo-Yuan Qu, Jordan Cotler, Fei Ma +7
By engineering and manipulating quantum entanglement between incoming photons and experimental apparatus, we construct single-photon detectors which cannot distinguish between phot…
Quantum Virtual Cooling
Jordan Cotler, Soonwon Choi, Alexander Lukin +10
We propose a quantum information based scheme to reduce the temperature of quantum many-body systems, and access regimes beyond the current capability of conventional cooling techn…
