(c) What quantum state do you have to input in order to get output 1/√2(00>+11>)?

Quantum Physics  Awesome Dude, Monday, March 18, 2013 at 3:17am
a) 1/sqrt(2) 0
0 1/sqrt(2)

Quantum Physics  helpman, Monday, March 18, 2013 at 7:14am
please (b) and (c)

Quantum Physics  Anonymous, Monday, March 18, 2013 at 10:06am
b is:
0 1/sqrt(2)
1/sqrt(2) 0
what is the answer to 13?

Quantum Physics  what's (c), Monday, March 18, 2013 at 10:56am
what's (c)

Quantum Physics  Gyano, Monday, March 18, 2013 at 12:56pm
c please
the answer for 13 is c

c)
1/2 1/2
1/2 1/2
Are you sure 13 is c?

ANSWERS TO QUESTIONS 1,9,14?

Quantum Physics  TIGER, Monday, March 18, 2013 at 7:02pm
I calculated this for the Q1:
(2+i+i^2)/6
But is not OK! some suggestion?

Quantum Physics  Anonymous, Monday, March 18, 2013 at 9:18pm
14d

Quantum Physics  TIGER, Monday, March 18, 2013 at 10:50pm
thks !! 9a... some help?ยก

Quantum Physics  Anonymous, Monday, March 18, 2013 at 10:52pm
Yes 9A?

Quantum Physics  TIGER, Monday, March 18, 2013 at 10:55pm
9b is 0.5
9a?????
and 1???

Quantum Physics  Maverick, Monday, March 18, 2013 at 11:01pm
Q1 is (3+5*i)/6
Down to my last entry on 9A???anyone?

Quantum Physics  TIGER, Monday, March 18, 2013 at 11:16pm
IM in the same situation.. is not:
0.5
neither
0.25
Probably 1?

Quantum Physics  SyLaR, Monday, March 18, 2013 at 11:16pm
9a is 1

Quantum Physics  TIGER, Monday, March 18, 2013 at 11:25pm
thank you!!! its correct...

Quantum Physics  Maverick, Monday, March 18, 2013 at 11:27pm
Arigato!

Quantum Physics  TIGER, Monday, March 18, 2013 at 11:57pm
