Generating nonlinearities from conditional linear operations, squeezing and measurement for quantum computation and super-Heisenberg sensing
Mattias T. Johnsson, Pablo M. Poggi, Marco A. Rodríguez +2
Large optical nonlinearities can have numerous applications, ranging from the generation of cat-states for optical quantum computation, through to quantum sensing where the sensiti…
All-Optical Long-Distance Quantum Communication with Gottesman-Kitaev-Preskill qubits
Kosuke Fukui, Rafael N. Alexander, Peter van Loock
Quantum repeaters are a promising platform for realizing long-distance quantum communication and thus could form the backbone of a secure quantum internet, a scalable quantum netwo…
Blueprint for a Scalable Photonic Fault-Tolerant Quantum Computer
J. Eli Bourassa, Rafael N. Alexander, Michael Vasmer +10
Photonics is the platform of choice to build a modular, easy-to-network quantum computer operating at room temperature. However, no concrete architecture has been presented so far…
Continuous-variable gate teleportation and bosonic-code error correction
Blayney W. Walshe, Ben Q. Baragiola, Rafael N. Alexander +1
We examine continuous-variable gate teleportation using entangled states made from pure product states sent through a beamsplitter. We show that such states are Choi states for a (…
Quantum-Computing Architecture based on Large-Scale Multi-Dimensional Continuous-Variable Cluster States in a Scalable Photonic Platform
Bo-Han Wu, Rafael N. Alexander, Shuai Liu +1
Quantum computing is a disruptive paradigm widely believed to be capable of solving classically intractable problems. However, the route toward full-scale quantum computers is obst…
Computational universality of symmetry-protected topologically ordered cluster phases on 2D Archimedean lattices
Austin K. Daniel, Rafael N. Alexander, Akimasa Miyake
What kinds of symmetry-protected topologically ordered (SPTO) ground states can be used for universal measurement-based quantum computation in a similar fashion to the 2D cluster s…
