  • Before picking up the phone and calling a technician to fix a faulty microwave oven, there are always a few simple things one should check. So far, “stop looking at it” has not been part of the checklist.

  • Optical loss degrades quantum correlations, hindering the use of quantum quadrature entanglement for many applications. Researchers have now experimentally demonstrated that this entanglement can be recovered using photon subtraction.

  • This paper theoretically and experimentally demonstrates a protocol that allows the generation of arbitrarily large squeezed Schrödinger cat states, using homodyne detection and photon number states as resources. The protocol was implemented with light pulses containing two photons, producing a squeezed Schrödinger cat state with a negative Wigner function.

  • Quantum superpositions of coherent light waves offer several advantages for quantum-information processing compared to single photons. A novel scheme for generating these so-called Schrödinger-cat states circumvents problems arising from their fragility, which has been a key obstacle towards applications.

  • Non-Gaussian Wigner-negative freely propagating optical quantum states are deterministically generated with a 60% photon generation efficiency. An evolution from quadrature squeezing to Wigner negativity is observed by changing the qubit rotation angle.
