There are high hopes for quantum computers: they are supposed to perform specific calculations much faster than current supercomputers and, therefore, solve scientific and practical problems that are insurmountable for ordinary ...
While conventional computers store information in the form of bits, fundamental pieces of logic that take a value of either 0 or 1, quantum computers are based on qubits. These can have a state that is simultaneously both ...
Some phases of matter cannot be described using the conventional framework of symmetry breaking and exhibit a so-called quantum order. One type of quantum order, known as topological order, is characterized by long-range ...
Quantum computers, devices that can perform computations relying on the principles of quantum mechanics, are expected to outperform classical computers on some types of optimization and processing tasks. While physicists ...
Used as a versatile material in industry and health care, magnesium oxide may also be a good candidate for quantum technologies. Research led by the U.S. Department of Energy's (DOE) Argonne National Laboratory and published ...
Can you prove whether a large quantum system truly behaves according to the weird and wonderful rules of quantum mechanics—or if it just looks like it does? In a new study, physicists from Leiden, Beijing and Hangzhou found ...
On July 8, 2025, physicists from Aalto University in Finland published a transmon qubit coherence measurement in Nature Communications that dramatically surpasses previous scientifically published records. The millisecond ...
Understanding randomness is crucial in many fields. From computer science and engineering to cryptography and weather forecasting, studying and interpreting randomness helps us simulate real-world phenomena, design algorithms ...
Devices taking advantage of the collective quantum behavior of spin excitations in magnetic materials—known as magnons—have the potential to improve quantum computing devices. However, using magnons in quantum devices requires ...
Developing technology that allows quantum information to be both stable and accessible is a critical challenge in the development of useful quantum computers that operate at scale. Research published in the journal Nature ...
