- Cisco has built a Quantum Network Controller, a research prototype that lets an application ask a quantum network for entanglement and leaves the network to work out the delivery. Entanglement, a linked quantum state shared between distant points, is the resource these networks distribute, and…
- The work could help improve quantum computers’ accuracy in complex calculations
- Error correction creates qubits that glitch only 5 out of a million times, the first step toward a new phase for quantum computing.

- Quantum computers, computer systems that leverage the laws of quantum mechanics, store and process information using qubits (i.e., quantum bits). In many quantum computers, qubits are linked via entanglement, a quantum mechanical effect that connects particles in such a way that their shared state…
- Physicists in the Department of Physics at the University of Oxford have used a hybrid quantum computer, made up of qubits and quantum oscillators, to observe the Aharonov–Bohm effect in a quantum simulation. The effect is a quantum phenomenon in which a particle can acquire a measurable phase by…
- Many of nature's most important processes depend on how particles of matter interact with light and other force-carrying particles. So far, however, it has proven difficult for conventional computers to determine how individual particles behave in these interactions.
- Researchers from Rutgers, IBM and collaborating institutions have shown that a quantum computer can check what is happening inside it and respond while it is running, repeatedly resetting parts of the system to bring chaotic behavior under control.
- Quantum information systems could one day shape everyday life through faster computing, sharper sensing and more secure communication. A new result from the U.S. Department of Energy's (DOE) Argonne National Laboratory and the University of Illinois Urbana-Champaign (U. of I.) marks an important…
- A major software advance could aid the creation of bigger, more reliable quantum computers, a study suggests. Researchers have developed an algorithm that enables off-the-shelf computers to run quantum simulations previously only possible using the world's most powerful supercomputers.
- When light hits a tiny defect embedded in a solid material like diamond or silicon carbide, it can kick the defect's electrons into an excited state. These spin defects have the potential to be used as stable, readable qubits for quantum technologies, for example, quantum sensing. But modeling the…
- The researchers in the Quantum Detection Microscopy group at CIC nanoGUNE, in collaboration with chemists at CiQUS of the University of Santiago de Compostela, have demonstrated that adding or removing a single molecule from a quantum chain can fundamentally change its interaction with a…
- Quantum computers represent a next step in the fast-paced evolution of technology. Using quantum bits (qubits), they have the potential to run certain calculations exponentially faster than conventional computers. However, developing and fine-tuning quantum computers requires an enormous number of…
- Qubits, the quantum equivalent of digital bits, are fragile and prone to errors. That makes building reliable quantum computers extremely difficult. One fix has been to use traditional magic state distillation, which filters out flaws, but it is extremely resource-intensive.
- Some quantum systems are so complex that even the most powerful supercomputers struggle to simulate their behavior. One solution is quantum simulation: building a controllable quantum system in the lab and tuning it to mimic the one researchers want to understand.
