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…
The Universe as a Quantum Encoder
Jordan Cotler, Andrew Strominger
Quantum mechanical unitarity in our universe is challenged both by the notion of the big bang, in which nothing transforms into something, and the expansion of space, in which some…
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…
Gravitational Constrained Instantons
Jordan Cotler, Kristan Jensen
We find constrained instantons in Einstein gravity with and without a cosmological constant. These configurations are not saddle points of the Einstein-Hilbert action, yet they con…
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…
AdS wormholes from a modular bootstrap
Jordan Cotler, Kristan Jensen
In recent work we computed the path integral of three-dimensional gravity with negative cosmological constant on spaces which are topologically a torus times an interval. Here we e…
