Measuring Entangled Qutrits and Their Use for Quantum Bit Commitment
Nathan K. Langford, Rohan B. Dalton, Michael D. Harvey +5
We produce and holographically measure entangled qudits encoded in transverse spatial modes of single photons. With the novel use of a quantum state tomography method that only req…
Quantum computation with optical coherent states
T. C. Ralph, A. Gilchrist, G. J. Milburn +2
We show that quantum computation circuits using coherent states as the logical qubits can be constructed from simple linear networks, conditional photon measurements and "small" co…
Photon Added Detection
A. M. Branczyk, Tobias J. Osborne, Alexei Gilchrist +1
The production of conditional quantum states and quantum operations based on the result of measurement is now seen as a key tool in quantum information and metrology. We propose a…
Generating optical nonlinearity using trapped atoms
Alexei Gilchrist, G. J. Milburn, W. J. Munro +1
We describe a scheme for producing an optical nonlinearity using an interaction with one or more ancilla two-level atomic systems. The nonlinearity, which can be implemented using…
Input states for quantum gates
A. Gilchrist, W. J. Munro, A. G. White
We examine three possible implementations of non-deterministic linear optical cnot gates with a view to an in-principle demonstration in the near future. To this end we consider de…
