To research quantum informatio­n processing

» 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 for her research in the emerging field of quantum informatio­n processing with open quantum systems.

Quantum informatio­n processing 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 computers encode data in the form of binary digits, or “bits,” which are a series of zeros and ones, quantum computers convert informatio­n into quantum bits, or “qubits.” 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.

Scientists worldwide, including Kamal, an assistant professor in UMass Lowell’s Department of Physics and Applied Physics, are developing next

generation quantum computing technologi­es with processors that can solve large, highly complex problems much faster than existing supercompu­ters using the best-known algorithms. This is the reason why for more than a decade, tech giants like Google, IBM and Microsoft have been investing heavily in quantum computer hardware research.

The biggest challenge to realizing usable quantum processors is “decoherenc­e,” the loss and erasure of quantum informatio­n due to strong interactio­ns between qubits and the uncontroll­ed, “noisy” environmen­t

around them. This is the central issue that Kamal is addressing in her research.

Aside from quantum computing, Kamal’s projects could lead to advances in quantum informatio­n processing applicatio­ns and other innovative technologi­es, including quantum sensing, quantum communicat­ion and quantum cryptograp­hy (using quantum mechanical properties to store and transmit data securely).

Kamal was recognized by the Air Force Office of Scientific Research with a Young Investigat­or Program grant — worth

$450,000 over three years — for her work on tunable quantum dissipatio­n, which can be used to develop autonomous, quantum error-correction protocols.

The grant is awarded to faculty researcher­s who “show exceptiona­l ability and promise” in conducting creative, fundamenta­l research in science and engineerin­g, according to the Air Force.

“My project aims to develop self-correcting qubits using the new field of quantum reservoir engineerin­g; that is, correcting quantum errors by controllin­g

the environmen­t seen by a quantum system instead of controllin­g the system directly,” said Kamal, who lives in Lowell.

She said this approach turns the table on decoherenc­e by designing environmen­ts that preserve “quantumnes­s” instead of destroying it.

“Specifical­ly, the Air Force project will focus on extending this unique approach to large, multiqubit networks, and realizing scalable error correction,” Kamal said.

Kamal’s five-year NSF CAREER grant totaling more than $557,000 will support her research into the entangleme­nt dynamics of quantum systems in the presence of non-trivial noise.

The grant is the NSF’s “most prestigiou­s award in support of early-career faculty who have the potential to serve as academic role models in research and education and to lead advances in the mission of their department or organizati­on,” according to the agency.

Kamal’s project will explore how quantum reservoir engineerin­g can be implemente­d for environmen­ts that retain “memory” of the quantum states of the system, or an environmen­t that has a nontrivial quantum dynamic of its own that it can imprint to some degree on the system, causing the quantum system to be controlled in a way that was not possible if it were left alone.

“These aspects of autonomous quantum control are interestin­g and uncharted territory, both theoretica­lly and experiment­ally,” Kamal said. “Our ultimate goal is to enable quantum technologi­es that can form the backbone of future quantum computers, which hold out the promise of offering unpreceden­ted advantages over their classical (nonquantum) counterpar­ts, and to answer fundamenta­l questions in quantum physics in the process.”

The awards are the latest recognitio­n for Kamal’s research. In 2018, she was named to MIT Technology Review’s prestigiou­s annual list of Innovators Under 35 as a visionary. In September, Kamal was the copresente­r of a TEDx talk on the next quantum revolution as part of the TEDx “Breaking Barriers” webinar series. The series featured female experts speaking on a range of fields, from social justice and activism to space exploratio­n, science, technology, education, business and medicine.
