"Creating highly scalable entangled states for the quantum computer"Moran Chen , University of Virginia [Host: GPSA]
ABSTRACT:
The quantum computer, whose information is encoded in "qubitsâ obeying quantum mechanics laws, will be able to perform some calculations exponentially faster than the classical computer whose information is encoded in "bitsâ. There are two principal models of quantum computing: the circuit model and the measurementbased model. The measurementbased model is crucially based on the cluster state, a type of highly entangled quantum state that serves as the resource and material for the whole calculation. This talk will discuss an original experimental work for the largest cluster state ever created whose modes (optical versions of qubits) are all available simultaneously. The entanglement proceeds from interfering multiple EPR pairs generated from a nonlinear crystal in an optical parametric oscillator, into a very long dualrail wire cluster state. These highly scalable cluster states serve as building blocks of the universal quantum computer, and also are important resources for studying quantum mechanics in large systems.
