Quantum computation with quantum dots [PDF]
Physical Review A, 1998 We propose a new implementation of a universal set of one- and two-qubit gates for quantum computation using the spin states of coupled single-electron quantum dots. Desired operations are effected by the gating of the tunneling barrier between neighboring dots.

Quantum Gravity on a Quantum Computer? [PDF]
Foundations of Physics, 2013 EPR-type measurements on spatially separated entangled spin qubits allow one, in principle, to detect curvature. Also the entanglement of the vacuum state is affected by curvature. Here, we ask if the curvature of spacetime can be expressed entirely in terms of the spatial entanglement structure of the vacuum.

Quantum computing enhanced computational catalysis [PDF]
Physical Review Research, 2020 The quantum computation of electronic energies can break the curse of dimensionality that plagues many-particle quantum mechanics. It is for this reason that a universal quantum computer has the potential to fundamentally change computational chemistry ...

Entangled states shaping with CV states of definite parity
Scientific Reports, 2022 We present a new method to entangle continuous variable (CV) states of certain parity and photonic states for the purpose of generating optical hybrid cluster (HC) states. To do it we introduce two families of the CV states of definite parity which stems

How to Compute Using Quantum Walks [PDF]
EPTCS 315, 2020, pp. 1-17, 2020 Quantum walks are widely and successfully used to model diverse physical processes. This leads to computation of the models, to explore their properties. Quantum walks have also been shown to be universal for quantum computing. This is a more subtle result than is often appreciated, since it applies to computations run on qubit-based quantum computers ...

Measurement-only verifiable blind quantum computing with quantum input verification
, 2016 Verifiable blind quantum computing is a secure delegated quantum computing where a client with a limited quantum technology delegates her quantum computing to a server who has a universal quantum computer.

Quantum picturalism for topological cluster-state computing
, 2020 Topological quantum computing is a way of allowing precise quantum computations to run on noisy and imperfect hardware. One implementation uses surface codes created by forming defects in a highly-entangled cluster state.

An Universal Quantum Network - Quantum CPU [PDF]
, 1999 An universal quantum network which can implement a general quantum computing is proposed. In this sense, it can be called the quantum central processing unit (QCPU). For a given quantum computing, its realization of QCPU is just its quantum network. QCPU
