German Scientists Create 5 qubit Quantum Register

Posted by timothy on from the sehr-klein dept.

CMan0 writes "In the University of Bonn, a team of scientists has built a 5 qubit register, using cesium atoms trapped by a laser-beam grid, The Register reports. They've been able to install an empty 5 bit register(i.e. all bits 0), change two of them to 1, and later read those 1s back. The next goal is to create an interaction between 2 bits. The full scientific article can be found here in PDF format."

    Actually, there was uncertainty.

    Upon further observation, it was known to have a probability of 1 ;)

    On a serious note, this is awesome. With a 5 qubit entanglement and this, we might be able to build a primitive functional Quantum Computer, for the first time.

    The team is now working to create a quantum gate in which two or more qubits of the register will interact in a controlled way.

    Amazing. The beginnings of a first QC. We've memory, redundancy, processing capabilities and a lot more.

    Now the only problem that remains is a suitable and reliable means of error correction - which is the biggest problem thus far in QC :-(
