Breakthrough for Quantum Measurement
said_captain_said_wo writes to tell us that PhysicsWeb is reporting that two teams of physicists have developed a new method for measuring the state of quantum bits in a quantum computer without disturbing the state. From the article: "In the future, the Josephson capacitance could be used for operations in a large-scale quantum computer," says Mika Sillanpaa of Helsinki University. "The Josephson inductance and Josephson capacitance together would also allow us to build new types of quantum 'band engineered' electronic devices, such as low-noise parametric amplifiers."
I'm not sure
Maybe. Maybe not, who can tell?
Task Mangler
Does this mean that we can find out if the cat is dead without opening the box? Sure sounds like it.
IANASPP (I Am Not A Sub-atomic Particle Physicist) but this seems to be quite a breakthrough that might save millions of subatomic cats from untimely deaths...
Anybody with some actual knowledge care to elucidate?
I have no problem with your religion until you decide it's reason to deprive others of the truth.
Heisenburg's Uncertainty Principle - DxDp>=hbar/2 Or as my old prof used to say "When you've got energy, you don't have the time. And when you've got the time, you don't have the energy."
You changed the state of the quantum bits by measuring them
The only things certain in war are Propaganda and Death. You can never be sure which is which though
Quantum computing is also good for solving problems in quantum mechanics. No, really.
I changed the article by reading it! Someone tell me what it says now...?
Netcraft confirms it, Schrödingers cat is dead.
