Meanwhile, UT researchers throughout campus are main discoveries in quantum supplies, quantum computing, quantum sensing and a complete vary of advances tied to how atoms and electrons behave on the smallest of scales and the way they work together with mild.
Quantum will not be a phrase you employ every single day, however quantum science performs a number one function in your on a regular basis experiences within the trendy world. Understanding quantum mechanics allowed earlier researchers to anticipate what electrons would do in silicon –– which in flip enabled the event of semiconductors and all of the computing gadgets that use them. Ditto for the connection between quantum mechanics and a complete suite of different applied sciences, starting from MRIs to GPS.
Now, scientists and engineers consider a brand new set of advances are proper across the nook when it comes to computing, medical science and clear vitality –– with the subsequent technology of applied sciences leaning on quantum discoveries and advances from UT and around the globe.
The quantum analysis facility beneath development now will assist determine new quantum phases of matter and represents only one instance of thoughts-bending quantum analysis from UT that dates to the Nineteen Seventies and is equally sturdy at this time.
Here, we are going to journey by way of time, explaining the milestones of quantum science grounded by UT and introduce ongoing quantum analysis on the University that guarantees to unlock continued improvements. To assist illustrate the quantum leaps with hyperlinks to the University, we’re spotlighting a number of the historical past, college members and initiatives reworking this area.
Earlier Theoretical Physicists Helped Put UT on the Quantum Discovery Map
The famend UT physicist John A. Wheeler developed the sector’s understanding of quantum demolition, a sort of measurement in quantum mechanics that provides information a couple of system however finally disrupts or destroys the quantum state being measured. The group of graduate and postdoctoral college students he skilled additionally made important contributions to the sector, reminiscent of theoretical physicist David Deutsch, who pioneered the sector of quantum computing by laying out mathematical ideas for a common quantum laptop. This led him to be dubbed the “father of quantum computing,” though it was a few years later earlier than the primary quantum laptop was constructed. Quantum computing makes use of properties of tiny particles, reminiscent of atoms, to clear up advanced issues that normal computer systems can’t deal with.

Another pioneer in Wheeler’s circle was Wojciech Zurek (Ph.D. ’79), who developed the idea of decoherence in quantum mechanics. Quantum decoherence disrupts fragile quantum states earlier than they are often harnessed for helpful computations. In addition, he cofounded the sector of quantum-error correction, which encodes quantum information to detect and repair errors. Zurek continues to be conducting quantum analysis as a laboratory fellow at Los Alamos National Laboratory in New Mexico.
Another Wheeler protégé could possibly be the topic of a possible “Jeopardy!” query within the science class: Who got here up with the time period “qubit,” the time period for a part that processes and shops info in a quantum laptop? Answer: Benjamin Schumacher (Ph.D. ’90).
According to Science News, Schumacher launched the notion of a little bit of quantum info, or a qubit, in a paper he offered throughout the early Nineteen Nineties.
“Schumacher worked out more than just a clever name [qubit]; he proved a theorem about how qubits could be used to quantify the quantum information sent through a communication channel,” Sciences News reported.
Current Physicist Allan MacDonald Made the UT Discovery That Has Inspired Labs Around the Globe
Fifteen years in the past, theoretical physicist Allan MacDonald, the Sid W. Richardson Foundation Regents Chair in Physics #1 at UT, gave a breakthrough twist to the fields of quantum physics and materials science.
In 2011, MacDonald and postdoctoral researcher Rafi Bistritzer revealed findings about their investigation of what occurs when two sheets of graphene — fabricated from a single layer of carbon atoms — are stacked with a slight rotational offset.
MacDonald and Bistritzer carried out their analysis utilizing supercomputers at UT’s Texas Advanced Computing Center. Their simulations revealed that at a exact 1.1-diploma twist, electrons gradual dramatically and behave in uncommon methods, a discovery that spawned the sector of twistronics (twisted two-dimensional supplies).
In 2018, scientists on the Massachusetts Institute of Technology confirmed that graphene organized at MacDonald’s “magic angle” can superconduct at much less excessive temperatures than what’s required for superconductors at this time. (Superconductivity refers to electrical present flowing with out the lack of vitality.) This discovering has paved the way in which for developments in quantum computing and vitality effectivity.
In recognition of his twistronics analysis, MacDonald shared the 2020 Wolf Prize in Physics with Bistritzer, now a physics professor at Tel Aviv University, and Pablo Jarillo-Herrero, an experimental physicist at MIT; earlier this yr MacDonald and Jarillo-Herrero had been awarded the Frontiers of Knowledge Award. Both prizes are among the many prime worldwide awards a physicist can obtain.
MacDonald stated many milestones have been achieved because the discovery of the “magic angle,” however crucial is the power to deliberately twist two sheets of supplies at any angle, not simply at 1.1 levels.
This higher management of twist angles affords “a new and very powerful way” of adjusting the properties of electrons inside 2D supplies and the interplay of these properties with mild, MacDonald stated. This could lead on to developments in fiber-optic information transfers and quantum computing, he stated.
Computer Scientist Scott Aaronson Defines Emerging Possibilities and Boundaries of Quantum Computing
Computer science theorist Scott Aaronson, UT’s David J. Bruton Jr. Centennial Professor of Computer Science, is a number one authority on quantum supremacy, an idea he helped develop. It refers to the power of a quantum machine to clear up an issue {that a} conventional laptop can’t clear up in an affordable period of time. And he set forth most of the theoretical foundations of quantum supremacy experiments.
In recognition of his work in quantum supremacy, Aaronson acquired the 2020 ACM Prize in Computing and was lately elected to the National Academy of Sciences, a prime-tier honor within the area of computing. Quantum supremacy, which depends on the ideas of quantum mechanics, holds the potential to yield breakthroughs in sectors reminiscent of prescribed drugs, semiconductors and vitality, and it additionally redraws the boundaries of computing.
Aaronson and his UT analysis group aren’t making an attempt to construct a analysis-grade quantum laptop. (They value anyplace from $10 million to $50 million to construct.) Instead, group members consider answering the query: “What can we do and what can we not do with a quantum computer?”
“Most of what we do is theory,” stated Aaronson, “but if we have any experiment that is worth doing, which sometimes we do, we can call up whoever on Earth has the best hardware to … run our experiment.”
In his prize-successful analysis, Aaronson confirmed that parts of computational complexity principle can illuminate key facets of quantum physics, serving to outline the boundaries and capabilities of quantum computer systems.
How Texas Quantum Institute Is Charting the Course of Quantum Research at UT
Fifty years after John A. Wheeler’s arrival in Austin, what’s on the horizon for quantum analysis on the University?
Elaine Li, a physicist holding a Welch Foundation Chair in Science, co-directs the Texas Quantum Institute (TQI), an umbrella group for the University’s quantum analysis. Among different objectives, she and her co-director (Xiuling Li, Truchard Foundation Endowed Chair in Electrical and Computer Engineering) need to increase quantum analysis carried out at UT and accomplice with others to assemble a quantum initiative consistent with different work on campus and throughout the state.
The University has taken massive steps in recent times. First, in 2023, quantum applied sciences firm Infleqtion signed a memorandum of understanding with Texas Institute for Electronics for improvement of qNexus, a middle of excellence for quantum manufacturing. Then in late 2025, Gov. Greg Abbott introduced a $4.8 million Texas Semiconductor Innovation Fund grant for TQI to set up the Qlab, a quantum-enhanced semiconductor metrology facility in Austin. “Metrology has been identified by the U.S. Department of Commerce as the key enabling technology for the semiconductor industry,” Li stated. This facility shall be managed by TQI in collaboration with UT-MRSEC, Microelectronics Research Center and Texas Materials Institute.
These developments are the newest chapter amid the myriad improvements in UT’s storied historical past of quantum analysis, which has developed properly past the times of John A. Wheeler. Today, as University researchers are exploring areas reminiscent of quantum algorithms, quantum supplies and quantum metrology, the promise of a brand new technological period beckons.
“We like to say we’re at the onset of the second quantum revolution,” Elaine Li added. “The first quantum revolution happened last century, and that’s made a lot of technology possible. The second quantum revolution may do even more.”
