Researchers have demonstrated that the theoretically optimal scaling for magic state distillation—a critical bottleneck in fault-tolerant quantum computing—is achievable for qubits, improving on the previous best result by ...
Quantum computers, machines that process information leveraging quantum mechanical effects, could outperform classical computers on some optimization tasks and computations. Despite their potential, quantum computers are ...
Quantum computers are powerful, lightning-fast and notoriously difficult to connect to one another over long distances.
The National Institute of Information and Communications Technology (NICT) has successfully demonstrated entanglement swapping (one of the key quantum communication protocols) using sum-frequency generation (SFG) between ...
In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today's best versions.
The path toward realizing practical quantum technologies begins with understanding the fundamental physics that govern quantum behavior—and how those phenomena can be harnessed in real materials.
An international team of scientists from three continents led by Dr. Petr Cígler of IOCB Prague has developed a method for creating light-emitting quantum centers in nanodiamonds in only a matter of minutes. In just one week, ...
Detecting dark matter—the mysterious substance that holds galaxies together—is one of the greatest unsolved problems in physics. Although it cannot be seen or touched directly, scientists believe dark matter leaves weak signals ...
With the rise of quantum computers, the security of our existing communication systems is at risk. Quantum computers will be able to break many of the encryption methods used in current communication systems. To counter this, ...
The world is filled with rotating objects—gyroscopes, magnetic spins, and more recently, qubits in quantum computers. For example, the atomic nuclei in our bodies precess at megahertz frequencies inside NMR machines. In practice, ...
