CU Boulder ready to leverage legacy in quantum science for technological advancement听
In the mid-20th century, physicists at Bell Laboratories ignited a technological renaissance with the invention of the transistor, an innovation that ushered in the digital age and is arguably one of the most significant technological advancements in human history.听
This relatively small device harnessed the principles of quantum mechanics to govern electric currents within semiconductor materials, rendering cumbersome vacuum tubes obsolete. It triggered a wave of advancements that are at the core of all modern communications and computing, as well as nearly every technology in use today.听
Today, researchers stand at the threshold of a new quantum era. 鈥淨uantum 2.0鈥� is distinguished not just by incremental technological evolution but by the untapped potential of melding deep quantum science with cutting-edge engineering.听
鈥淭hough over a century old, quantum technology is undergoing a transformative phase. The first generation of quantum technology 鈥� relied on individual quantum听particles. Now, we are working on quantum physics, which needs a combination of quantum particles to work together,鈥� said Jun Ye, professor adjoint in the Department of Physics, JILA associate fellow and fellow at the National Institute of Standards and Technology. 鈥淭his shift will open avenues to revolutionary new technologies and applications.鈥澨�
CU Boulder and the College of Engineering and Applied Science are at the forefront of that quantum frontier, leveraging a rich legacy in quantum science and fostering a vibrant ecosystem where academic researchers, government and research laboratories and industry leaders collaborate to transform theories into real-world applications.听
CU鈥檚 bold initiatives have the potential to revolutionize sectors as diverse as aerospace, defense, healthcare and energy, offering innovative new approaches to tackle global challenges like climate change.听
The Quantum Engineering Initiative (QEI), under the auspices of the broader CU Boulder CUbit Initiative and led by CU Engineering, is specifically chartered to advance 鈥渇oundational quantum science into practical technologies and ... prepare the workforce for the quantum industry,鈥� said Scott Diddams, QEI director and professor of electrical, computer and energy engineering. 鈥淏ut we鈥檙e not just riding the wave of quantum advancements; we鈥檙e actively shaping it.鈥澨�
Diddams鈥檚 work, particularly in optical frequency metrology and laser frequency combs, is at the heart of QEI鈥檚 efforts and crucial to bridging theoretical quantum physics with practical applications. It opens new avenues in timekeeping, navigation and environmental monitoring.听
Diddams has deep expertise in quantum sensing, which harnesses quantum phenomena for high-precision measurement of physical quantities such as time, frequency, length, magnetic fields and gravitational waves.听
Quantum sensors have the potential to greatly enhance GPS accuracy and advance environmental and health diagnostics 鈥� and even fundamental quantum research itself. He also sees significant potential in quantum computing and secure communication technologies.听
Greg Rieker, associate director of CUbit and associate professor of mechanical engineering, stands out for his practical application of quantum science.听
Leveraging research from his Precision Laser Diagnostics Lab, Rieker launched a startup, LongPath Technologies, which specializes in advanced laser technology for environmental sensing, focusing on methane emission detection.听
鈥淨uantum is the new 鈥榮pace race,鈥欌�� Rieker said. 鈥淚t鈥檚 the technologies developed on the pathway to big leaps like quantum computing that will find practical applications.鈥澨�
In the world of quantum computing, where hype has often exceeded realities, Corey Rae McRae, a research professor of electrical, computer and energy engineering and a project leader at NIST Boulder, takes a grounded approach.听
Her Boulder Cryogenic Quantum Testbed, established with funding from Google Quantum AI, is focused on improving the materials used in qubit construction 鈥� developing precise metrological techniques for these materials to improve efficiency and stability.听
An integral part of McRae鈥檚 work is the development of specialized toolkits that aim to standardize and streamline quantum computing research and establish CU Boulder as a key contributor to setting standards in the quantum computing field.听
Diddams acknowledges the obstacles on the horizon of Quantum 2.0 technology, but he remains optimistic.听
鈥淐U is really uniquely situated in this environment,鈥� he said. 鈥淲e鈥檙e poised to become a key player in Colorado鈥檚 鈥榪uantum valley.鈥欌�澨�
What is quantum science?听
Rooted in the enigmatic principles of quantum mechanics, it explores the realm of atoms and subatomic particles 鈥� shedding light on nature鈥檚 mysterious and often counterintuitive behaviors at its smallest scales. Central to this field are phenomena like superposition, where particles can simultaneously exist in multiple states, and entanglement, which allows particles to exhibit instantly correlated behaviors over long distances. By demystifying and harnessing these quantum behaviors, scientists and engineers are simultaneously deepening their understanding of the quantum world while paving the way for pioneering advancements in computing, communications, security, sensing techniques, novel materials and energy solutions.听
