Modular Entanglement Using Atomic Ion Qubits

JQI researchers demonstrated modular entanglement between two atomic systems, separated by one meter. Here, photons are the long distance information carriers entangling multiple qubit modules. Inside of a single module, quantized collective vibrations called phonons connect individual qubits. In the latest result, one module contains two qubits and a second module houses a single qubit.

Novel Phases for Bose Gases

JQI theorists have proposed a new magnetic phase for a bosonic gas. The transition to this phase is analogous to the formation of ferromagnetism in magnetic materials, like iron, and might give insight into the physics of strongly-correlated electronic systems.

Microfluidic Diamond Sensor

Measuring faint magnetic fields is a trillion-dollar business.  Gigabytes of data, stored and quickly retrieved from chips the size of a coin, are at the heart of consumer electronics.   Even higher data densities can be achieved by enhancing magnetic detection sensitivity---perhaps down to nano-tesla levels.

Michelson-Morley Experiment for Electrons

 A new experiment conducted at the University of California at Berkeley used quantum information techniques for a precision test of a cornerstone principle of physics, namely Lorentz invariance.  This precept holds that the results of a physics experiment do not depend on its absolute spatial orientation.  The work uses quantum-correlated electrons within a pair of calcium ions to look for shifts in quantum energy levels with unprecedented sensitivity.   JQI Adjunct Fellow and University of Delaware professor Marianna Safronova, who contributed a theoretical analysis of the data, said that

Rice-sized laser, powered one electron at a time, bodes well for quantum computing

Researchers from JQI and Princeton University have built a rice grain-sized microwave laser, or "maser," powered by single electrons that demonstrates the fundamental interactions between light and moving electrons.

Quantum Re-Coherence

Quantum computers will someday perform calculations impossible for conventional digital computers.  But for that to happen, the core quantum information must be preserved against contamination from the environment.  In other words, decoherence of qubits must be forestalled.  Coherence, the ability of a system to retain quantum integrity---meaning that one part of the system can be used to predict the behavior of other parts---is an important consideration.

Philip Merrill Presidential Scholars

JQI Fellows Christopher Monroe and Victor Yakovenko, were recognized as mentors of the high-achieving students Geoffrey Ji and Zachary Siegel (respectively), who were named the 2014-2015 Philip Merrill Presidential Scholars. Ji currently works ion trap quantum information in Monroe's group and Siegel works on ultracold atomic gases with Trey Porto.

Best Quantum Receiver

Alan Migdall and Elohim Becerra and their colleagues at the Joint Quantum Institute have devised an optical detection scheme with an error rate 25 times lower than the fundamental limit of the best conventional detector. They did this by employing not passive detection of incoming light pulses. Instead the light is split up and measured numerous times.
