World's Next Timekeeper: Quantum Superclock?
Atomic clocks would meet quantum entanglement

(Newser) – Sick of missing appointments by milliseconds because of inaccurate atomic clocks? Researchers say they could use quantum physics to create a timekeeper so accurate it could help explain some of the mysteries of time itself. The "quantum superclock" would involve multiple atomic clocks, each in its own satellite orbiting the Earth and each carrying pairs of linked particles entangled in such a way that "measuring a property of one of them instantaneously determines the same property for the other," Nature explains—a phenomenon known as "quantum entanglement" that Albert Einstein called "spooky action at a distance," notes Forbes. In the case of these satellites, a central satellite would fashion its clock particles in an entangled state, then extend the entanglement to another satellite, and so on, until the quantum network is created.

The linked clock would be far more accurate than anything that exists today, allowing for precise linking of financial markets, better space navigation, and even the detection of subtle shifts in space and time. The researchers say that in addition to measuring time, the quantum timepiece could measure the Earth's terrain so accurately that somebody digging a tunnel under the US-Mexican border could be spotted from space, Science News reports. Much research remains to be done before such a superclock can become a reality, but "we're trying to be a little bit visionary," says Harvard physicist Eric Kessler. "All the building blocks have been demonstrated in principle, and we want to show what might lie ahead if all these fields merge together." In the meantime, the US has unveiled what it says is the most accurate clock in the world.

We all need to be using UTC anyway because a time error in a computer system cost me from getting a better job last year. The agency I was seeking to work sent me a calendar reminder of the meeting instead of just sending me a text or email. For some reason, it translated the meeting time to NYT instead of CST. But I'm OCD on such things anyway so I was a full hour early to the location and was parking my car when my phone rang. It was the head dude asking where I was. I said I was parking and was going to walk around the facility. He said the committee was waiting for me in the conference room. I then grabbed my crap and headed there without straightening my hair, suit, etc. I got there all mussed up. Then the interview didn't go so well. Then I explained what must have happened. Then when the meeting was over, I sent them a screen shot of the calendar entry they sent me. The the only reply I got was the standard canned, "Sorry but not sorry."

It doesn't matter how accurate the clock is, my calendars won't sync so I'm always screwing up meetings.

the only SUPERCLOCK I have is the countdown to the NOVEMBER TO REMEMBER cause that's... When the DUMOCRATS LOSE & the REP WIN BIG on NOV 4, 2014!!!! CAUSE THE LEGAL USA RESIDENTS VOTERS KNOWS THAT TIME IS RUNNING OUT FOR THE DUMOCRATS &..... America is worth fighting for, to ensure future generations enjoy the same opportunities we’ve had to gain an education, get a job, start a family and live in peace, **UNHARRASSED BY A MEDDLING,CENTRALIZED MONOLITHIC GOVERNMENT IN TODAY'S USA***!!! ALSO.. Then in Nov. 08, 2016 Gov. Christie will be prez!!!! and everything will be AOK in the USA on Jan 20, 2017!! there ya go!! .
