Irfan Siddiqi received his AB (1997) in chemistry and physics from Harvard University. He then went on to receive a PhD (2002) in applied physics from Yale University, where he stayed as a postdoctoral researcher until 2005. Irfan joined the physics department at the University of California, Berkeley in the summer of 2006. In 2006, Irfan was awarded the George E. Valley, Jr. prize by the American Physical Society for the development of the Josephson bifurcation amplifier. In 2007, he was awarded the Office of Naval Research Young Investigator Award, the Hellman Family Faculty Fund, and the UC Berkeley Chancellor’s Partnership Faculty Fund.

Shay received his B.S from Tel-Aviv University where he also completed his Ph.D. He studied transport in Superconducting/Ferromagnetic junctions, as well as moonlighting with tunneling into graphene and High-Tc superconductors. Shay joined QNL in September 2012. He is currently working with Natania on the nanobridge SQUID magnetometer and with Vinay on arrays of transmons. Above all Shay loves his kids.

David received his B.S. from the University of Minnesota and his Ph.D. from the University of California, Santa Barbara. Working in David Awschalom's group, his Ph.D. research focused on nanoscale engineering, quantum control, and thermometry with nitrogen vacancy centers in diamond. David joined QNL in September 2013 and is working with Andrew on the next generation of on-chip parametric amplifiers for qubit measurement.

Natania graduated from MIT in 2009 with a S.B. in physics. She is working on coupling spin ensembles to superconducting devices, for ultimate use as a quantum memory. She is also working on using a nanobridge SQUID as a magnetometer to read out small numbers of spins. While she admits that she sometimes dances in lab, she also likes dancing outside of lab, along with rock climbing and hanging upside down from trapezes

Ned graduated from Harvard University in 2007 with an A.B. in Physics, and is currently working toward a Ph.D. at Berkeley. He is investigating coupling a solid state qubit to an electromagnetic resonator, hoping to facilitate coherent communication of quantum information over macroscopic length scales. He enjoys melted cheese.

Chris received his B.A. in physics from Cornell University in 2009. He is working on near-quantum-limited continuous measurement and quantum feedback control of superconducting qubits, and developing quantum-limited microwave amplifiers without resonant structures. Chris is also presently the QNL webmaster.

Mollie Schwartz joined QNL in 2011. She studies long-range entanglement of superconducting qubits, including the use of quantum-limited measurement to entangle remote, uncoupled qubits. Mollie graduated from Columbia University with a B.A. in Chemical Physics in 2009 and worked for two years as an analyst at the Science and Technology Policy Institute, a not-for-profit, nonpartisan think tank that supports the White House Office of Science and Technology Policy and other Executive offices and agencies. Outside of lab, Mollie teaches Israeli Folk Dancing and eats fancy cheese.
