LOWELL, Mass. â UMass Lowell researcher Archana Kamal has won two early career development awards totaling more than $1 million from the U.S. Air Force and the National Science Foundation (NSF) for her research in the emerging field of quantum information processing (QIP) with open quantum systems.
QIP is based on the principles of quantum mechanics, which mathematically describe the behavior and interaction of matter and light on the atomic and subatomic scale.
While todayâs digital computers encode data in the form of binary digits, or âbits,â which are a series of zeros and ones, quantum computers convert information into quantum bits, or âqubits.â A qubit, which is the basic unit of quantum information, represents a two-state, or two-level, quantum system, such as the up and down spin of an electron or the horizontal and vertical polarization of a photon.

Researchers at the National Institute of Standards and Technology (NIST) and collaborators have demonstrated an atom-based sensor that can determine the direction of an incoming radio signal, another key part for a potential atomic communications system that could be smaller and work better in noisy environments than conventional technology.
NIST researchers previously demonstrated that the same atom-based sensors can receive commonly used communications signals. The capability to measure a signal’s “angle of arrival” helps ensure the accuracy of radar and wireless communications, which need to sort out real messages and images from random or deliberate interference.
“This new work, in conjunction with our previous work on atom-based sensors and receivers, gets us one step closer to a true atom-based communication system to benefit 5G and beyond,” project leader Chris Holloway said.
