Witnessing mass-energy equivalence with trapped atom interferometers [PDF]

Quantum
We propose an experimental setup to probe the interplay between the quantum superposition principle and gravitational time dilation arising from the mass-energy equivalence.

Quantum computation with mesoscopic superposition states [PDF]

, 2000
We present a strategy to engineer a simple cavity-QED two-bit universal quantum gate using mesoscopic distinct quantum superposition states. The dissipative effect on the decoherence and the amplitude damping of the quantum bits are analyzed and the ...

A quantum phase transition in a quantum external field: Superposing two magnetic phases

, 2012
We study an Ising chain undergoing a quantum phase transition in a quantum magnetic field. Such a field can be emulated by coupling the chain to a central spin initially in a superposition state.

Quantum noise eater for a single photonic qubit

New Journal of Physics, 2013
We propose a quantum noise eater for a single qubit and experimentally verify its performance for recovery of a superposition carried by a dual-rail photonic qubit. We consider a case when only one of the rails (e.g.

Quantum superposition of boundary conditions in PAdS2 [PDF]

We explore the quantum superposition of boundary conditions in the context of the Poincaré patch of the two-dimensional anti–de Sitter space. Focusing on Robin (mixed) boundary conditions, we investigate the response function of the Unruh-DeWitt (UDW ...

Traces of Objectivity: Causality and Probabilities in Quantum Physics [PDF]

, 2011
It is pointed out that the probabilistic character of a theory does not indicate by itself a distancing with respect to the norms of objectification. Instead, the very structure of the calculation of probabilities utilised by this theory is capable of ...

Optimal superpositions for particle detection via quantum phase

Physical Review Research
Exploiting quantum mechanics for sensing offers unprecedented possibilities. State-of-the-art proposals for novel quantum sensors often rely on the creation of large superpositions and generally detect a field.

Reconstructing Reality: Environment-Induced Decoherence, the Measurement Problem, and the Emergence of Definiteness in Quantum Mechanics [PDF]

, 2008
This work is a critique of the program of "environment-induced decoherence" as advocated by Zurek, Zeh and Joos, among others. In particular, the alleged relevance of decoherence for a solution of the "measurement problem" is subjected to a detailed ...
