• Abstract summary: We exploit the full repetition rate and the ultrafast shaping of a femtosecond light source to combine, for the first time, frequency- and time- multiplexing in multimode squeezing. This paves the way to the implementation of multipartite entangled states that are both scalable and fully reconfigurable.

• Abstract: Spectral- and time- multiplexing are currently explored to generate large multipartite quantum states of light for quantum technologies. In the continuous variable approach, the deterministic generation of large entangled states demands the generation of a large number of squeezed modes. Here, we demonstrate the simultaneous generation of 21 squeezed spectral modes at 156 MHz. We exploit the full repetition rate and the ultrafast shaping of a femtosecond light source to combine, for the first time, frequency- and time- multiplexing in multimode squeezing. This paves the way to the implementation of multipartite entangled states that are both scalable and fully reconfigurable.

• A reconfigurable silicon photonics chip for the generation of frequency bin entangled qudits [0.0]
  Quantum optical microcombs in integrated ring resonators generate entangled photon pairs over many spectral modes. A promising strategy is the use of multiple resonators, each generating photon pairs in specific frequency bins via spontaneous four-wave mixing. We present a programmable silicon photonics device for the generation of frequency bin entangled qudits, in which bin spacing, qudit, and bipartite quantum state can be reconfigured on-chip.

• Towards a spectrally multiplexed quantum repeater [16.67624046004553]
  Extended quantum networks are based on quantum repeaters that often rely on entanglement in an efficient and heralded fashion over multiple network nodes. Many repeater architectures require multiplexed sources of entangled photon pairs, multiplexed quantum memories, and photon detection that distinguishes between the multiplexed modes. Here we demonstrate the concurrent employment of (1) spectrally multiplexed cavity-enhanced spontaneous parametric down-conversion in a nonlinear crystal; (2) a virtually-imaged phased array that enables mapping of spectral modes onto distinct spatial modes for frequency-selective detection; and (3) a cryogenically cooled Tm3+:LiNbO3 crystal that allows spectral filtering

  spatial modes of light provide a high-dimensional space that can be used to encode both classical and quantum information. Current approaches for dynamically generating and measuring these modes are slow, due to the need to reconfigure a high-resolution phase mask. We experimentally realize this approach, using a double-pass AOM to generate one of five orbital angular momentum states. We are able to reconstruct arbitrary states in under 1 ms with an average fidelity of 96.9%.

  Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protocols.

We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.

  Measuring the spectral properties of an optical frequency comb is among the most fundamental tasks of precision metrology. We demonstrate here single shot multi parameter estimation at and beyond the standard quantum limit. Using a quantum frequency comb that consists of multiple squeezed states in a family of Hermite-Gaussian spectral/temporal modes, the signal-to-noise ratios of the mean energy and the central frequency measurements surpass the shot-noise limit by around 19% and 15%, respectively.
