Experimental generation of multi-photon Fock states
Merlin Cooper, Laura J. Wright, Christoph Söller +1
We experimentally demonstrate the generation of multi-photon Fock states with up to three photons in well-defined spatial-temporal modes synchronized with a classical clock. The st…
Vanishing quantum discord is not necessary for completely-positive maps
Aharon Brodutch, Animesh Datta, Kavan Modi +2
The description of the dynamics of a system that may be correlated with its environment is only meaningful within the context of a specific framework. Different frameworks rely upo…
Topological quantum computing with a very noisy network and local error rates approaching one percent
Naomi H. Nickerson, Ying Li, Simon C. Benjamin
A scalable quantum computer could be built by networking together many simple processor cells, thus avoiding the need to create a single complex structure. The difficulty is that r…
Quantum sensors based on weak-value amplification cannot overcome decoherence
George C. Knee, G. Andrew D. Briggs, Simon C. Benjamin +1
Sensors that harness exclusively quantum phenomena (such as entanglement) can achieve superior performance compared to those employing only classical principles. Recently, a techni…
Strategies for enhancing quantum entanglement by local photon subtraction
Tim J. Bartley, Philip J. D. Crowley, Animesh Datta +3
Subtracting photons from a two-mode squeezed state is a well-known method to increase entanglement. We analyse different strategies of local photon subtraction from a two-mode sque…
Superdense Coding with GHZ and Quantum Key Distribution with W in the ZX-calculus
Anne Hillebrand
Quantum entanglement is a key resource in many quantum protocols, such as quantum teleportation and quantum cryptography. Yet entanglement makes protocols presented in Dirac notati…
