Quantum dots illuminate transport within the cell

Biophysicists from Utrecht University have developed a strategy for using light-emitting nanocrystals as a marker in living cells. By recording the movements of these quantum dots, they can clarify the structure and dynamics ...

Quantum RAM: Modelling the big questions with the very small

When it comes to studying transportation systems, stock markets and the weather, quantum mechanics is probably the last thing to come to mind. However, scientists at Australia's Griffith University and Singapore's Nanyang ...

Fast track control accelerates switching of quantum bits

From laptops to cellphones, today's technology advances through the ever-increasing speed at which electric charges are directed through circuits. Similarly, speeding up control over quantum states in atomic and nanoscale ...

An Archimedes' screw for groups of quantum particles

Anyone who has tried to lead a group of tourists through a busy city knows the problem. How do you keep the group together when they are constantly jostled, held up and distracted by the hubbub around them?

Harnessing the possibilities of the nanoworld

Scientists have long suspected that the way materials behave on the nanoscale – that is when particles have dimensions of about 1–100 nanometres – is different from how they behave on any other scale. A new paper in ...

Quantum computing advances with control of entanglement

When the quantum computer was imagined 30 years ago, it was revered for its potential to quickly and accurately complete practical tasks often considered impossible for mere humans and for conventional computers. But, there ...

Putting cells through their paces

The spheroid is the width of a few human hairs and made up of 25,000 human lung cells clustered together with iron particle, suspended in a fluid that runs though a microscopic obstacle course of channels sealed between glass.
