Quantum superposition and quantum entanglement are the bedrock on which new theoretical paradigms for information transmission, storage, and processing are being built. The preeminent obstacle to the development of  quantum information technology is the difficulty of transmitting quantum information over noisy and lossy quantum communication channels, recovering and refreshing the quantum information that is received, and then storing it in a reliable quantum memory.  

With support from the Multidisciplinary Research Program of the University Research Initiative (MURI), we have assembled a truly interdisciplinary team from researchers at MIT and Northwestern University to overcome this obstacle. The focus of our program is an architecture we have established for long-distance, high-fidelity qubit teleportation. Its key elements are:

ultrabright, narrowband sources of polarization-entangled photon pairs;

long-distance transmission of entangled photons over standard telecom fiber;

qubit storage and processing in trapped atom quantum memories.
