Photon Counting Distribution for Arrays of Single-Photon Detectors
Mattias Jönsson, Gunnar Björk
We derive a computationally efficient expression of the photon counting distribution for a uniformly illuminated array of single photon detectors. The expression takes the number o…
Evaluating Performance of Photon-Number-Resolving Detectors
Mattias Jönsson, Gunnar Björk
We analyze the performance of photon-number-resolving (PNR) detectors and introduce a figure of merit for the accuracy of such detectors. This figure of merit is the (worst-case) p…
Fidelity as a figure of merit in quantum error correction
Jonas Almlöf, Gunnar Björk
We discuss the fidelity as a figure of merit in quantum error correction schemes. We show that when identifiable but uncorrectable errors occur as a result of the action of the cha…
Experimental determination of the degree of quantum polarisation of continuous variable states
Christian Kothe, Lars Skovgaard Madsen, Ulrik Lund Andersen +1
We demonstrate excitation-manifold resolved polarisation characterisation of continuous-variable (CV) quantum states. In contrast to traditional characterisation of polarisation th…
On the efficiency of nondegenerate quantum error correction codes for Pauli channels
Gunnar Bjork, Jonas Almlof, Isabel Sainz
We examine the efficiency of pure, nondegenerate quantum-error correction-codes for Pauli channels. Specifically, we investigate if correction of multiple errors in a block is more…
Combating entanglement sudden death with non-local quantum-error correction
Isabel Sainz, Gunnar Bjork
We study the possibility of preventing finite-time disentanglement caused by dissipation by making use of "non-local quantum error correction. This is made in comparison of previou…
