Hydrogen as a superfluid

RobertBradbury writes "Scientists at Livermore have pushed the calculations on the phase state of hydrogen to the level that they think it may become a superfluid. Cold superfluids are of interest in nanotechnology because they could enable advanced cooling methods for nanocomputers or the operation of devices at temperatures that support more robust quantum computing. The classical superfluid is of course helium but now it looks as if hydrogen under the right conditions could be as well. The only question is how much diamondoid is required to sustain a pressure of 4 million atmospheres?"
