There are days when I wish quantum cryptography was a mature, installed, technology. Today is one of those days. Why? You might think its because I’m a quantum obsessed physicist whose daily sustenance depends on the future of quantum information science. But no. Today I wish quantum cryptography were installed because today the Supreme Court rejected a challenge to the Bush administration’s domestic spying program;

The Supreme Court rejected a challenge Tuesday to the Bush administration’s domestic spying program.
The justices’ decision, issued without comment, is the latest setback to legal efforts to force disclosure of details of the warrantless wiretapping that began after the Sept. 11 attacks.
The American Civil Liberties Union wanted the court to allow a lawsuit by the group and individuals over the wiretapping program. The 6th U.S. Circuit Court of Appeals dismissed the suit, saying the plaintiffs could not prove their communications had been monitored

If only the ACLU’s clients had been using quantum cryptography, then they would know that their phone lines were being tapped, and they would have the record to prove it. Of course what the judges probably really meant was that the plaintiffs could not prove their communication had been monitored by the government’s domestic spying plan. Sadly, quantum cryptographers have yet to develop a method for identifying the name of the attacker when eavesdropping occurs on quantum key distribution.
