Quantum state tomography of undetected photons
Jorge Fuenzalida, Jaroslav Kysela, Krishna Dovzhik +4
The measurement of quantum states is one of the most important problems in quantum mechanics. We introduce a quantum state tomography technique in which the state of a qubit is rec…
Arbitrary unitaries in orbital angular momentum of single photons
Jaroslav Kysela
A simple argument is presented that explicitly shows how to construct an arbitrary quantum gate acting on orbital angular momentum (OAM) of single photons. The scheme can be applie…
High-dimensional quantum Fourier transform of twisted light
Jaroslav Kysela
The Fourier transform proves indispensable in the processing of classical information as well as in the quantum domain, where it finds many applications ranging from state reconstr…
Fourier Transform of the Orbital Angular Momentum of a Single Photon
Jaroslav Kysela, Xiaoqin Gao, Borivoje Dakić
Optical networks implementing single-qudit quantum computation gates may exhibit superior properties to those for qubits as each of the optical elements in the network can work in…
Deterministic Twirling with Low Resources
David Jakob Stonner, Jaroslav Kysela, Graeme Weir +3
Twirling operations, which average a quantum state with respect to a unitary subgroup, have become a frequently-employed tool in quantum information processing. We investigate the…
Experimental High-Dimensional Entanglement by Path Identity
Jaroslav Kysela, Manuel Erhard, Armin Hochrainer +2
Versatile and high-brightness sources of high-dimensional entangled photon pairs are important for emerging quantum technologies such as secure quantum communication. Here, we expe…
Arbitrary d-dimensional Pauli X-Gates of a flying Qudit
Xiaoqin Gao, Mario Krenn, Jaroslav Kysela +1
High-dimensional degrees of freedom of photons can encode more quantum information than their two-dimensional counterparts. While the increased information capacity has advantages…
