Achieving the ultimate quantum timing resolution
Vahid Ansari, Benjamin Brecht, Jano Gil-López +5
Accurate time-delay measurement is at the core of many modern technologies. Here, we present a temporal-mode demultiplexing scheme that achieves the ultimate quantum precision for…
Remotely projecting states of photonic temporal modes
Vahid Ansari, John M. Donohue, Benjamin Brecht +1
Two-photon time-frequency entanglement is a valuable resource in quantum information. Resolving the wavepacket of ultrashort pulsed single-photons, however, is a challenge. Here, w…
Pulse shaping using dispersion-engineered difference frequency generation
Markus Allgaier, Vahid Ansari, John Matthew Donohue +5
The temporal-mode (TM) basis is a prime candidate to perform high-dimensional quantum encoding. Quantum frequency conversion has been employed as a tool to perform tomographic anal…
High-performance source of spectrally pure, polarization entangled photon pairs based on hybrid integrated-bulk optics
Evan Meyer-Scott, Nidhin Prasannan, Christof Eigner +4
Entangled photon pair sources based on bulk optics are approaching optimal design and implementation, with high state fidelities, spectral purities and heralding efficiencies, but…
Quantum-limited time-frequency estimation through mode-selective photon measurement
John M. Donohue, Vahid Ansari, Jaroslav Řeháček +5
By projecting onto complex optical mode profiles, it is possible to estimate arbitrarily small separations between objects with quantum-limited precision, free of uncertainty arisi…
Ultrafast quantum interferometry with energy-time entangled photons
Jean-Philippe W. MacLean, John M. Donohue, Kevin J. Resch
Many quantum advantages in metrology and communication arise from interferometric phenomena. Such phenomena can occur on ultrafast time scales, particularly when energy-time entang…
