Fundamental quantum optics experiments conceivable with satellites - reaching relativistic distances and velocities
Physical theories are developed to describe phenomena in particular regimes, and generally are valid only within a limited range of scales. For example, general relativity provides an effective
Classical verification of quantum circuits containing few basis changes
TLDR
The task of verifying the correctness of quantum computation for a restricted class of circuits which contain at most two basis changes is considered, and it is shown that, when the circuit has an outcome with probability at least the inverse of some polynomial in the circuit size, the outcome can be checked inPolynomial time with bounded error.
Universality of quantum computation with cluster states and (X, Y)-plane measurements
TLDR
This work examines the question of whether the requirement for Z measurements can be dropped while maintaining universality in MBQC and answers this question in the affirmative by showing that universality is possible in this scenario.
Flow ambiguity: A path towards classically driven blind quantum computation
TLDR
This work shows how a classical client can exploit the ambiguity in the flow of information in measurement-based quantum computing to construct a protocol for hiding critical aspects of a computation delegated to a remote quantum computer.
Anonymous broadcasting of classical information with a continuous-variable topological quantum code
Broadcasting information anonymously becomes more difficult as surveillance technology improves, but remarkably, quantum protocols exist that enable provably traceless broadcasting. The difficulty is
Detecting topological entanglement entropy in a lattice of quantum harmonic oscillators
The Kitaev surface code model is the most studied example of a topologically ordered phase and typically involves four-spin interactions on a two-dimensional surface. A universal signature of this
Client-friendly continuous-variable blind and verifiable quantum computing
We present a verifiable and blind protocol for assisted universal quantum computing on continuous-variable (CV) platforms. This protocol is highly experimentally-friendly to the client, as it only
Continuous-variable topological quantum codes enable anonymous broadcasting of classical information
Broadcasting information anonymously becomes more difficult as surveillance technology improves, but remarkably, quantum protocols exist that enable provably traceless broadcasting. The difficulty is
Photon polarization and geometric phase in general relativity
Rotation of polarization in an external gravitational field is one of the effects of general relativity that can serve as a basis for its precision tests. A careful analysis of reference frames is
Pedagogical introduction to the entropy of entanglement for Gaussian states
The most useful measure of a bipartite entanglement is the von Neumann entropy of either of the reduced density matrices. For a particular class of continuous-variable states, the Gaussian states,
