Selective detection of signal over noise is essential to measurement and signal processing.
Time-frequency filtering has been the standard approach for the optimal detection of non …

All classical and quantum technologies that encode in and retrieve information from optical
fields rely on the ability to selectively manipulate orthogonal field modes of light. Such …

We experimentally demonstrate a programmable parametric mode sorter of high-
dimensional signals in a composite spatiotemporal Hilbert space through mode-selective …

Manipulating the frequency and bandwidth of nonclassical light is essential for implementing
frequency-encoded/multiplexed quantum computation, communication, and networking …

The temporal shape of single photons provides a high-dimensional basis of temporal
modes, and can therefore support quantum computing schemes that go beyond the qubit …

Phase-sensitive detection is the essential projective measurement for measurement-based
continuous-variable quantum information processing. The bandwidth of conventional …

The time-frequency degree of freedom is a powerful resource for implementing high-
dimensional quantum information processing. In particular, field-orthogonal pulsed temporal …

The dynamics of quantum systems are unavoidably influenced by their environment, but in
turn observing a quantum system (probe) can allow one to measure its environment …

We experimentally demonstrate spectral broadening and shaping of exponentially-decaying
nanosecond pulses via nonlinear mixing with a phase-modulated pump in a periodically …

The quantum noise of light, attributed to the random arrival time of photons from a coherent
light source, fundamentally limits optical phase sensors. An engineered source of squeezed …
