Optimizing efficiency of quantum circuits

Quantum circuits, the building blocks of quantum computers, use quantum mechanical effects to perform tasks. They are much faster and more accurate than the classical circuits that are found in electronic devices today. In ...

Cryo-chip overcomes obstacle to large-scale quantum computers

QuTech has resolved a major issue on the road toward a working large-scale quantum computer. QuTech, a collaboration of TU Delft and TNO, and Intel have designed and fabricated an integrated circuit that can controlling qubits ...

Pushing quantum photonics

Quantum computers use the fundamentals of quantum mechanics to potentially speed up the process of solving complex computations. Suppose you need to perform the task of searching for a specific number in a phone book. A classical ...

Introducing quantum convolutional neural networks

Machine learning techniques have so far proved to be very promising for the analysis of data in several fields, with many potential applications. However, researchers have found that applying these methods to quantum physics ...

Heterostructure crystals could light the way to optical circuits

It may be possible to reach new levels of miniaturization, speed, and data processing with optical quantum computers, which use light to carry information. For this, we need materials that can absorb and transmit photons. ...

Granular aluminum for future computers

Computers based on quantum mechanical principles can solve certain tasks particularly efficiently. Their information carriers, the so-called qubits, not only have the values "0" and "1," but also states in between, called ...

Researchers lead breakthrough in quantum computing

The large, error-correcting quantum computers envisioned today could be decades away, yet experts are vigorously trying to come up with ways to use existing and near-term quantum processors to solve useful problems despite ...

How electronic skin could help people with disabilities

You might not know what they're called, but you probably use them quite a lot. Virtual buttons, also called soft keys, are on smartphones, ATMs and computer monitors, doing the work of buttons though they are just an image.
