One of the biggest challenges in quantum technology and quantum sensing is “noise”–seemingly random environmental disturbances that can disrupt the delicate quantum states of qubits, the fundamental units of quantum information. Looking deeper at this issue, JILA Associate Fellow and University of Colorado Boulder Physics Assistant Professor Shuo Sun collaborated with Andrés Montoya-Castillo, Assistant Professor … Read more
They say that one can miss the forest for the trees. But it’s often worth taking a closer look at the trees to make sense of the dense, brambly whole. That’s what a Stanford University group did to tackle a thorny quantum-information problem in diamond. A star material for hosting quantum information, diamond nevertheless presents … Read more
Quantum information science is truly fascinating—pairs of tiny particles can be entangled such that an operation on either one will affect them both even if they are physically separated. A seemingly magical process called teleportation can share information between different far-flung quantum systems. These different systems can be coupled using quantum processes to form quantum … Read more
Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom “recoils” in the opposite direction, making it difficult to measure the position and momentum of the atom precisely. This recoil can have big implications for quantum sensing, … Read more
Scientists have introduced a form of quantum entanglement known as frequency-domain photon number-path entanglement. This advance in quantum physics involves an innovative tool called a frequency beam splitter, which has the unique ability to alter the frequency of individual photons with a 50% success rate. For years, the scientific community has delved into spatial-domain photon … Read more
Quantum mechanics is one of the most profound and revolutionary theories in modern physics, unraveling the mysteries of the subatomic world and fundamentally transforming our understanding of matter, energy, and the fundamental forces of nature. Developed in the early 20th century through the works of pioneering physicists such as Max Planck, Albert Einstein, Niels Bohr, … Read more
The question of where the boundary between classical and quantum physics lies is one of the longest-standing pursuits of modern scientific research, and in new research published today, scientists demonstrate a novel platform that could help us find an answer. The laws of quantum physics govern the behavior of particles at miniscule scales, leading to … Read more

Researchers from the University of Chicago’s Pritzker School of Molecular Engineering, led by Giulia Galli, have conducted a groundbreaking computational study aimed at predicting the conditions necessary to create specific spin defects in silicon carbide. Their findings, recently published in Nature Communications, mark a significant milestone in the quest to understand and optimize the fabrication … Read more
For years, scientists have been striving to extend the duration of quantum bits, or qubits, maintaining their delicate quantum states. This endeavor is pivotal in the development of quantum technologies like sensors, gyroscopes, and memory devices. A team of physicists at MIT, led by Ju Li and Paola Cappellaro, made a significant leap in this … Read more
Scientists have made a breakthrough in studying the unique exciton states found in two-dimensional tungsten disulfide (WS2) crystals. These excitons, which are composed of an electron and an electron hole, have short lifetimes and can rapidly transition between different states. By employing a new technique called time-resolved momentum microscopy, researchers have been able to track … Read more
