Efficient generation of spatially delocalised entangledstates is at the heart of quantum information science. Generally,flying qubits are proposed for long range entangling interactions,however here we introduce a bus-mediated alternative for this task.Our scheme permits efficient and flexible generation ofdeterministic two-qubit operator measurements and has links to theimportant concepts of mode-entanglement and repeat-until-successprotocols. Importantly, unlike flying qubit protocols, our… 

Spatial adiabatic passage as a quantum wire

Qubit transport has been identified as vital in improving quantum error correction thresholds in scalable quantum computer architectures. Introducing practical transport in the solid-state is

Dark State Adiabatic Passage with Branched Networks and High-Spin Systems: Spin Separation and Entanglement

This work explores the extension of a particular protocol, dark state adiabatic passage, where a spin state is transported across a branched network of initialised spins, comprising one `input' spin, and multiple leaf spins.

Entangling unitary gates on distant qubits with ancilla feedback

By using an ancilla qubit as a mediator, two distant qubits can undergo a non-local entangling unitary operation. This is desirable for when attempting to scale up or distribute quantum computation

Spatial adiabatic passage: a review of recent progress

Recent progress on developing techniques for the preparation of spatial states through adiabatic passage is reviewed, particularly focusing on three state systems.

Spatial adiabatic passage in a realistic triple well structure

We investigate the evolution of an electron undergoing coherent tunneling via adiabatic passage (CTAP) using the solution of the one-dimensional Schrodinger equation in both space and time for a

Theoretical considerations of Bell-inequality experiments usually assume identically prepared and independent pairs of particles. Here we consider pairs that exhibit both intrapair and interpair

Parallel interaction-free measurement using spatial adiabatic passage

Interaction-free measurement (IFM) is a surprising consequence of quantum interference, where the presence of objects can be sensed without any disturbance of the object being measured. Here, we show

Coherent tunneling adiabatic passage with the alternating coupling scheme

This work investigates the properties of Coherent Tunneling Adiabatic Passage with alternating tunneling matrix elements, and introduces simplified coupling protocols, and transient eigenspectra as well as a realistic gate design for this transport protocol.

Top-down pathways to devices with few and single atoms placed to high precision

Solid-state devices that employ few and single atoms are emerging as a consequence of technological advances in classical microelectronics and proposals for quantum computers based on spin or charge.



Quantum-information transport to multiple receivers

The importance of transporting quantum information and entanglement with high fidelity cannot be overemphasized. We present a scheme based on adiabatic passage that allows for transportation of a

Repeat-until-success linear optics distributed quantum computing.

The possibility to perform distributed quantum computing using only single-photon sources (atom-cavity-like systems, linear optics, and photon detectors), which does not require explicit qubit-qubit interactions, a priori entangled ancillas, nor the feeding of photons into photon sources.

Quantum computation by communication

We present here a new approach to scalable quantum computing—a ‘qubus computer’—which realizes qubit measurement and quantum gates through interacting qubits with a quantum communication bus mode.

Architecture for a large-scale ion-trap quantum computer

This work shows how to achieve massively parallel gate operation in a large-scale quantum computer, based on techniques already demonstrated for manipulating small quantum registers, and uses the use of decoherence-free subspaces to do so.
