متن کاملMultimode interferometer for guided matter waves.
Atoms can be trapped and guided with electromagnetic fields, using nanofabricated structures. We describe the fundamental features of an interferometer for guided matter waves, built of two combined Y-shaped beam splitters. We find that such a device is expected to exhibit high contrast fringes even in a multimode regime, analogous to a white light interferometer.
متن کاملTime-reversal-symmetric single-photon wave packets for free-space quantum communication.
Readout and retrieval processes are proposed for efficient, high-fidelity quantum state transfer between a matter qubit, encoded in the level structure of a single atom or ion, and a photonic qubit, encoded in a time-reversal-symmetric single-photon wave packet. They are based on controlling spontaneous photon emission and absorption of a matter qubit on demand in free space by stimulated Raman...
متن کاملExperimental demonstration of time-delay interferometry for the laser interferometer space antenna.
We report on the first demonstration of time-delay interferometry (TDI) for LISA, the Laser Interferometer Space Antenna. TDI was implemented in a laboratory experiment designed to mimic the noise couplings that will occur in LISA. TDI suppressed laser frequency noise by approximately 10(9) and clock phase noise by 6×10(4), recovering the intrinsic displacement noise floor of our laboratory tes...
متن کاملLong-distance frequency-division interferometer for communication and quantum cryptography.
We introduce and demonstrate experimentally a single-channel long-distance interferometer that utilizes frequency division of two optical waves by using acousto-optic devices at the transmitting and receiving nodes of the interferometer. This novel single-channel long-distance interferometer provides unity visibility of the interference and therefore is useful not only for remote sensing and op...
