Magnetic resonance goes nano

June 1, 2005 | Source: Technology Research News

Japanese researchers have built a nuclear magnetic resonance (NMR) device that has the potential to overcome the current quantum-computng limit of 10 quantum bits.

It could also allow NMR devices to be used in chemistry, biology and medicine to examine smaller samples.

The device measures electron spin by measuring electrical resistance across a 200-by-200-nanometer area of semiconductor material rather than using a centimeter-scale coil to pick up radio waves.

The researchers’ next step is to fabricate a quantum integrated circuit by connecting several nuclear magnetic resonance devices for use as quantum memory.
