Deterministic reshaping of single-photon spectra using cross-phase modulation
The frequency conversion of light has proved to be a crucial technology for communication, spectroscopy, imaging, and signal processing. In the quantum regime, it also offers great potential for realizing quantum networks incorporating disparate physical systems and quantum-enhanced information processing over a large computational space. The frequency conversion of quantum light, such as singl...
متن کاملLarge conditional single-photon cross-phase modulation.
Deterministic optical quantum logic requires a nonlinear quantum process that alters the phase of a quantum optical state by π through interaction with only one photon. Here, we demonstrate a large conditional cross-phase modulation between a signal field, stored inside an atomic quantum memory, and a control photon that traverses a high-finesse optical cavity containing the atomic memory. This...

متن کاملRemoving cross-phase modulation from midinfrared chirped-pulse upconversion spectra.
We observe that narrow spectral features in mid-infrared spectra obtained by chirped-pulse up-conversion are strongly distorted by cross-phase modulation between the mid-infrared field and the chirped pulse. We discuss the consequences of this effect on spectral resolution, and introduce a correction method that recovers masked lines. This simple correction can be applied either when the upconv...
متن کاملDeterministic Secure Direct Communication Using single photon resource
Quantum key distribution is a brilliant application of quantum mechanics. Two remote parties establish a shared secret key through the transmission of quantum states. We consider that quantum channel is secure because that quantum physics establishes a set of negative rules stating things that cannot be done: (1) One cannot take a measurement without perturbing the system. (2) One cannot determ...
