RE: Elementary fermions: the particles of matter… (Particle Physics Series – Episode 3A)
"Ultra fast computer based trading " seems like it will be the first practical application of entanglement, right now they all compete to see who can be physically closest to the exchange so they can trade faster than the other guy.
It has already been happening for years... unfortunately (Classical computers are way fast enough )
right but with a quantum communications you would not need to be physically close to the exchange, there would be no delay at all or advantage of physical proximity.
I think you might still have the old view of the exchange with people shouting orders... I am not 100% sure, but I believe 99.9% transactions now are carried out by computer (i.e. from any place in the world in any market in the world...).
my understanding is , if I have a trading computer and you have a trading computer and mine has a 1 picosecond delay and you are twice as far away and have a 2 picosecond delay then I win. But quantum communications would make it literally instantaneous, there is not any delay with entangled particles right?
Oh, but here you are talking about entanglement... it's more of a communication issue than quantum computer processing power... if 2 particles entangled, there would be no delay, would you be 2 blocks away or the other side of the universe ...
exactly
