A symmetry analyser for non-destructive Bell state detection using EIT
S. D. Barrett, P. Kok, K. Nemoto +3
We describe a method to project photonic two-qubit states onto the symmetric and antisymmetric subspaces of their Hilbert space. This device utilizes an ancillary coherent state, t…
Efficient high-fidelity quantum computation using matter qubits and linear optics
Sean D. Barrett, Pieter Kok
We propose a practical, scalable, and efficient scheme for quantum computation using spatially separated matter qubits and single photon interference effects. The qubit systems can…
Relativistic quantum communication with bosonic and fermionic interferometers
Pieter Kok, Samuel L. Braunstein
We derive the relativistic transformation laws for the annihilation operators of the scalar field, the massive spin-1 vector field, the electromagnetic field and the spinor field.…
Comment on: "Measuring a Photonic Qubit without Destroying It"
Pieter Kok, William J. Munro
Recently, Pryde et al reported the demonstration of a quantum non-demolition scheme for single-photon polarization states with linear optics and projective measurements [Phys. Rev.…
Communicating continuous quantum variables between different Lorentz frames
Pieter Kok, Timothy C. Ralph, Gerard J. Milburn
We show how to communicate Heisenberg-limited continuous (quantum) variables between Alice and Bob in the case where they occupy two inertial reference frames that differ by an unk…
Quantum lithography, entanglement and Heisenberg-limited parameter estimation
Pieter Kok, Samuel L. Braunstein, Jonathan P. Dowling
We explore the intimate relationship between quantum lithography, Heisenberg-limited parameter estimation and the rate of dynamical evolution of quantum states. We show how both th…
