Quantum Neural Networks for a Supply Chain Logistics Application
Randall Correll, Sean J. Weinberg, Fabio Sanches +2
Problem instances of a size suitable for practical applications are not likely to be addressed during the noisy intermediate-scale quantum (NISQ) period with (almost) pure quantum…
Reinforcement Learning for Multi-Truck Vehicle Routing Problems
Joshua Levin, Randall Correll, Takanori Ide +3
Deep reinforcement learning (RL) has been shown to be effective in producing approximate solutions to some vehicle routing problems (VRPs), especially when using policies generated…
Supply Chain Logistics with Quantum and Classical Annealing Algorithms
Sean J. Weinberg, Fabio Sanches, Takanori Ide +2
Noisy intermediate-scale quantum (NISQ) hardware is almost universally incompatible with full-scale optimization problems of practical importance which can have many variables and…
Short Quantum Circuits in Reinforcement Learning Policies for the Vehicle Routing Problem
Fabio Sanches, Sean Weinberg, Takanori Ide +1
Quantum computing and machine learning have potential for symbiosis. However, in addition to the hardware limitations from current devices, there are still basic issues that must b…
Radial Cutoffs and Holographic Entanglement
Brianna Grado-White, Donald Marolf, Sean J. Weinberg
Tensor networks, , and broader notions of a holographic principle all motivate the idea that some notion of gravitational holography should persist in the presence of a r…
DAYENU: A Simple Filter of Smooth Foregrounds for Intensity Mapping Power Spectra
Aaron Ewall-Wice, Nicholas Kern, Joshua S. Dillon +14
We introduce DAYENU, a linear, spectral filter for HI intensity mapping that achieves the desirable foreground mitigation and error minimization properties of inverse co-variance w…
Gauge-invariant observables in gravity and electromagnetism: black hole backgrounds and null dressings
Steven B. Giddings, Sean Weinberg
We address questions regarding construction and implications of gauge-invariant "dressed" observables in nontrivial background geometries such as that of a black hole. Formally, su…
Holographic Shannon Entropy: The Outer Entropy of Entanglement Wedges
Sean J. Weinberg
We introduce a simple geometrical construction similar to covariant holographic entanglement entropy but with the addition of a new term proportional to boundary region volume. Thi…
Maximin is Not Enough
Massimiliano Rota, Sean J. Weinberg
The RT formula for static spacetimes arising in the AdS/CFT correspondence satisfies inequalities that are not yet proven in the case of the HRT formula, which applies to general d…
The Boundary Dual of Bulk Local Operators
Fabio Sanches, Sean J. Weinberg
We provide a procedure to determine if a given nonlocal operator in a large N holographic CFT is dual to a local bulk operator on the geometry associated with a particular code sub…
Toward a Holographic Theory for General Spacetimes
Yasunori Nomura, Nico Salzetta, Fabio Sanches +1
We study a holographic theory of general spacetimes that does not rely on the existence of asymptotic regions. This theory is to be formulated in a holographic space. When a semicl…
Spacetime Equals Entanglement
Yasunori Nomura, Nico Salzetta, Fabio Sanches +1
We study the Hilbert space structure of classical spacetimes under the assumption that entanglement in holographic theories determines semiclassical geometry. We show that this sim…
Refinement of the Bousso-Engelhardt Area Law
Fabio Sanches, Sean J. Weinberg
Past holographic screens are codimension-one surfaces of indefinite signature that are foliated by marginally anti-trapped surfaces called leaves. Future holographic screens are de…
A Holographic Entanglement Entropy Conjecture for General Spacetimes
Fabio Sanches, Sean J. Weinberg
We present a natural generalization of holographic entanglement entropy proposals beyond the scope of AdS/CFT by anchoring extremal surfaces to holographic screens. Holographic scr…
Flat-space Quantum Gravity in AdS/CFT
Yasunori Nomura, Fabio Sanches, Sean J. Weinberg
Motivated by the task of understanding microscopic dynamics of an evolving black hole, we present a scheme describing gauge-fixed continuous time evolution of quantum gravitational…
The Black Hole Interior in Quantum Gravity
Yasunori Nomura, Fabio Sanches, Sean J. Weinberg
We discuss the interior of a black hole in quantum gravity, in which black holes form and evaporate unitarily. The interior spacetime appears in the sense of complementarity becaus…
Relativeness in Quantum Gravity: Limitations and Frame Dependence of Semiclassical Descriptions
Yasunori Nomura, Fabio Sanches, Sean J. Weinberg
Consistency between quantum mechanical and general relativistic views of the world is a longstanding problem, which becomes particularly prominent in black hole physics. We develop…
Black Holes, Entropies, and Semiclassical Spacetime in Quantum Gravity
Yasunori Nomura, Sean J. Weinberg
We present a coherent picture of the quantum mechanics of black holes. The picture does not require the introduction of any drastically new physical effect beyond what is already k…
The Entropy of a Vacuum: What Does the Covariant Entropy Count?
Yasunori Nomura, Sean J. Weinberg
We argue that a unitary description of the formation and evaporation of a black hole implies that the Bekenstein-Hawking entropy is the "entropy of a vacuum": the logarithm of the…
Black Holes or Firewalls: A Theory of Horizons
Yasunori Nomura, Jaime Varela, Sean J. Weinberg
We present a quantum theory of black hole (and other) horizons, in which the standard assumptions of complementarity are preserved without contradicting information theoretic consi…
Low Energy Description of Quantum Gravity and Complementarity
Yasunori Nomura, Jaime Varela, Sean J. Weinberg
We consider a framework in which low energy dynamics of quantum gravity is described preserving locality, and yet taking into account the effects that are not captured by the naive…
Black Holes, Information, and Hilbert Space for Quantum Gravity
Yasunori Nomura, Jaime Varela, Sean J. Weinberg
A coarse-grained description for the formation and evaporation of a black hole is given within the framework of a unitary theory of quantum gravity preserving locality, without dro…
Complementarity Endures: No Firewall for an Infalling Observer
Yasunori Nomura, Jaime Varela, Sean J. Weinberg
We argue that the complementarity picture, as interpreted as a reference frame change represented in quantum gravitational Hilbert space, does not suffer from the "firewall paradox…
