Quantum communication with ultrafast time-bin qubits
Frédéric Bouchard, Duncan England, Philip J. Bustard +2
The photonic temporal degree of freedom is one of the most promising platforms for quantum communication over fiber networks and free-space channels. In particular, time-bin states…
Achieving ultimate noise tolerance in quantum communication
Frédéric Bouchard, Duncan England, Philip J. Bustard +4
At the fundamental level, quantum communication is ultimately limited by noise. For instance, quantum signals cannot be amplified without the introduction of noise in the amplified…
Two-photon interference: the Hong-Ou-Mandel effect
FrédÉric Bouchard, Alicia Sit, Yingwen Zhang +5
Nearly 30 years ago, two-photon interference was observed, marking the beginning of a new quantum era. Indeed, two-photon interference has no classical analogue, giving it a distin…
Underwater quantum communication over a 30-meter flume tank
Felix Hufnagel, Alicia Sit, Frédéric Bouchard +5
Underwater quantum communication has recently been explored using polarization and orbital angular momentum. Here, we show that spatially structured modes, e.g., a coherent superpo…
Geometric phase from Aharonov-Bohm to Pancharatnam-Berry and beyond
Eliahu Cohen, Hugo Larocque, Frederic Bouchard +3
Whenever a quantum system undergoes a cycle governed by a slow change of parameters, it acquires a phase factor: the geometric phase. Its most common formulations are known as the…
High-dimensional quantum gates using full-field spatial modes of photons
Florian Brandt, Markus Hiekkamäki, Frédéric Bouchard +2
Unitary transformations are the fundamental building blocks of gates and operations in quantum information processing allowing the complete manipulation of quantum systems in a coh…
