A study by physicists at the Technical University of Munich (TUM) has shown how nanotubes can store information in the form of vibrations.

Using quantum mechanical phenomena, computers could be much more powerful than their classical digital predecessors.

Up to now, researchers have experimented primarily with electrically charged particles. But because nanomechanical devices are not charged, they are much less sensitive to electrical interference.

To date most systems are based on electrically charged particles that are held in an “electromagnetic trap.” A disadvantage of these systems is that they are very sensitive to electromagnetic interference and therefore need extensive shielding. Physicists at TUM have now found a way for information to be stored and quantum mechanically processed in mechanical vibrations.

A carbon nanotube that is clamped at both ends can be excited to oscillate. Like a guitar string, it vibrates more than a million time, allowing information to be retained for up to one second.

Since such a string oscillates among many physically equivalent states, the physicists resorted to a trick: an electric field in the vicinity of the nanotube ensures that two of these states can be selectively addressed. The information can then be written and read optoelectronically.

A look at what quantum computing can do.

Quantum storage and computing are just around the corner. Look here to see what Quantum Computing is all about.

Physicists successfully store two-frame ‘movie’ in atomic cloud

A team from the National Institute of Standards and Technology has successfully stored two frames of a simple “movie” in a cloud of rubidium gas for the first time. Atomic storage is one vital aspect of quantum networks, and rubidium vapor has been one of the most promising media. 

A breakthrough in quantum computing.

Researchers claim quantum breakthrough

Researchers say they have designed a tiny crystal that acts like a quantum computer so powerful it would take a computer the size of the known universe to match it.

Details of the crystal, which is made up of just 300 atoms, are published today in the journal Nature.

“Quantum computing is a kind of information science that is based on the notion that if one performs computations in a fundamentally different way than the way your classical desktop computer works,” says study co-author University of Sydney’s Dr Michael Biercuk.

“There’s a huge potential to solve a variety of problems that are very, very hard or near impossible for standard computer.”

The crystal simulator uses a property of quantum mechanics called superposition, where a quantum particle appears to be in two distinct states at the same time. This means the particle, known as a qubit, can be used to solve two equations simultaneously.

As the number of qubits increase, the number or states increases exponentially. For example, 2 qubits can simultaneously be in 4 states, 3 qubits in 8 states: 2 to the power of n states for n qubits.

So what exactly is Quantum Computing and why is it important?

"A quantum computer is a device for computation that makes direct use of quantum mechanical phenomena, such as superposition and entanglement, to perform operations on data. Quantum computers are different from digital computers based on transistors. Whereas digital computers require data to be encoded into binary digits (bits), quantum computation utilizes quantum properties to represent data and perform operations on these data." - Quantum Computing - Wikipedia
The Bloch sphere is a representation of a qubit, the fundamental building block of quantum computers.

What this means is that the processing speed of computing rises enormously. Instead of storage on transistors, data is stored on atoms. With the increase in processing speed, larger and more advanced artificial intelligences (AI) become possible.
