To build a global quantum communication network, low-transmission, fiber-based communication channels can be supplemented by using a free-space channel between a satellite and a ground station on Earth. We have constructed a system that generates hyperentangled photonic "ququarts" and measures them to execute multiple quantum communication protocols of interest. We have successfully executed and characterized superdense teleportation, a modified remote-state preparation protocol that transfers…

Towards hyperentangled time-bin and polarization superdense teleportation in space

Quantum communication networks based on fiber optics are restricted in length since efficient quantum repeaters are not yet available. A free-space channel between a satellite in orbit and Earth can…

Hyperentangled Time-Bin and Polarization Quantum Key Distribution

Fiber-based quantum key distribution (QKD) networks are currently limited without quantum repeaters. Satellite-based QKD links have been proposed to extend the network domain. We have developed a…

Remote preparation of a general single-photon hybrid state

Feasible time-bin entanglement purification based on sum-frequency generation.

This paper presents the first entanglement purification protocol (EPP) for time-bin entangled state, which does not require the sophisticated controlled-not (CNOT) gate or similar operations, and it uses the feasible sum-frequency generation (SFG) to perform the purification.

648-Hilbert space dimensionality in biphoton frequency combs for quantum-secure communications and networks

The Hilbert space dimensionality is increased and a 648- dimensional Hilbert spaces with time-frequency entanglement in a biphoton frequency comb is demonstrated, enabling a computational space up to 13 photonic qubits, and 6.28 bits/photon classical information capacity.

Observing quantum coherence from photons scattered in free-space

A novel approach to transfer and recover quantum coherence from scattered, non-line-of-sight photons analyzed in a multimode and imaging interferometer for time-bins, combined with photon detection based on a 8 × 8 single-photon-detector-array is demonstrated.

Performance analysis of inter-satellite round-robin differential-phase-shift quantum key distribution

The results indicate that OAM encoding is preferable to time-bin encoding only under the circumstances where a low dimension and a large receiver aperture are used, but it is found that TM encoding is the best encoding scheme in RRDPS QKD over an inter-satellite channel.

Superdense teleportation using hyperentangled photons

This work uses photon pairs hyperentangled in polarization and orbital angular momentum to implement superdense teleportation, which can communicate a specific class of single-photon ququarts and demonstrates that this set has an exponentially larger state space volume than the lower-dimensional general states with the same number of state parameters.

Ground-to-satellite quantum teleportation

The demonstration of a ground-to-satellite uplink for reliable and ultra-long-distance quantum teleportation is an essential step towards a global-scale quantum internet.

SuperDense Quantum Teleportation

This paper is the write-up of the remarks at the Festschrift conference for Anton Zeilinger, for many years a close collaborator in the Hampshire College NSF grant continuing the authors' work with Mike Horne and Danny Greenberger started under Cliff Shull at MIT in the late 20th century.

Experimental Satellite Quantum Communications.

The scheme paves the way toward the implementation of a QC worldwide network leveraging existing receivers by exploiting satellite corner cube retroreflectors as quantum transmitters in orbit and the Matera Laser Ranging Observatory of the Italian Space Agency as a quantum receiver.

Satellite-based entanglement distribution over 1200 kilometers

Satellite-based distribution of entangled photon pairs to two locations separated by 1203 kilometers on Earth, through two satellite-to-ground downlinks is demonstrated, with a survival of two-photon entanglement and a violation of Bell inequality.

Quantum teleportation of multiple degrees of freedom of a single photon

This work uses photon pairs entangled in both degrees of freedom (that is, hyper-entangled) as the quantum channel for teleportation, and develops a method to project and discriminate hyper-ENTangled Bell states by exploiting probabilistic quantum non-demolition measurement, which can be extended to more degrees offreedom.

Progress towards implementing superdense teleportation in Space

New analysis of the received state reconstruction performance in the presence of high channel loss and multiple pair events is discussed and initial characterization of a waveguide-based entanglement source intended for space will be presented.

Satellite-to-ground quantum key distribution

This work reports the development and launch of a low-Earth-orbit satellite for implementing decoy-state QKD—a form ofQKD that uses weak coherent pulses at high channel loss and is secure because photon-number-splitting eavesdropping can be detected.
