How quantum algorithms solve problems that classical computers can’t

Quantum computers solve difficult problems efficiently using quantum gates and quantum algorithms. Shor's algorithm is an example of a quantum algorithm that is more efficient than classical algorithms for factorisation. Grover's algorithm is another quantum algorithm that is more efficient for searching large lists. The Deutsch-Jozsa algorithm is an example…

New ‘quantum engine’ does work by flipping the identity of atoms

Physicists have created a ‘quantum engine’ to convert the energy difference between two quantum states - fermionic and bosonic - of some atoms into work. The device adapts the principles of a classical engine to subatomic realm, allowing physicists to study quantum thermodynamics with better control and to potentially better…

Significance of quantum dots in nanotechnology | Explained

2023 Nobel Prize for chemistry explained | A quantum dot is a really small assembly of atoms (just a few thousand) around a few nanometres wide. Quantum dots have also been called ‘artificial atoms’ because the dot as a whole behaves like an atom in some circumstances.

What scientists find when they find nothing

Null results can yield profound insights: from Michelson-Morley's experiment leading to the special theory of relativity, to searches for dark matter particles prompting new theories. Null results can also be a sign of progress, as seen in the hunt for dark matter and new forces, and in experiments like LIGO.…
