Researchers program biomaterials with 'logic gates' that release therapeutics in response to environmental triggers

Drug treatments can save lives, but sometimes they also carry unintended costs. After all, the same therapeutics that target pathogens and tumors can also harm healthy cells.

Researchers implement 3-qubit Grover search on a quantum computer

Searching large, unordered databases for a desired item is a time-consuming task for classical computers, but quantum computers are expected to perform these searches much more quickly. Previous research has shown that Grover's ...

Researchers discover a valleytronics route towards reversible computer

In many two-dimensional (2-D) materials, electrons not only possess charge and spin, but further exhibit an unusual quantum feature. Electrons residing in many 2-D materials can live in well-separated energy minima, and the ...

Towards the separation of quantum and classical query complexities

Correlation functions are often employed to quantify the relationships among interdependent variables or sets of data. A few years ago, two researchers proposed a property-testing problem involving Forrelation for studying ...

A prototype for a spin-wave majority logic gate that uses wave interference for information processing

Computer electronics are shrinking to small-enough sizes that the very electrical currents underlying their functions can no longer be used for logic computations in the ways of their larger-scale ancestors. A traditional ...

Longest maths proof would take 10 billion years to read

An Anglo-American trio presented the prize-winning solution to a 35-year old maths problem Friday, but verifying it may be a problem in itself: reading it would take 10 billion years.
