## Dr. Geller Receives $2 Million NSF Grant to Construct Quantum Computer

February 18, 2011Physics Professor Michael Geller and a team of co-principal investigators including Physics Professor Phillip Stancil received a $2 million grant from the National Science Foundation to begin work on a quantum computer that could more efficiently and more rapidly solve problems in such fields as cryptography, mathematics and physics. Geller stated, "We will use this grant to develop and demonstrate a general purpose quantum simulator built from supercomputing electrical circuits."

The key to quantum computing is using clusters of data called qubits (for quantum bits) that handle data differently than conventional computers based on transistors. Traditional computers use a 1 or a 0 to represent "on" or "off" states, but a qubit, which can be constructed in different ways, can represent 1 and 0 states simultaneously in something called superposition.
