Quantum computation Definition and 71 Threads

I'm currently in my final year of BSc(Hons) in mathematics and computer science & A.I (applied math stream). Indeed, I'm starting to think about what masters I want to pursue and the kind of subject I would like to specialize in. I am really interested in quantum computation and the prospects of...

Hi everyone I am working on entanglement between an atomic system and its spontaneous emission but I don't know how to connect this kind of entanglement with quantum computation, I have read in different articles that entanglement is somehow essential in applications like quantum communication...

Next semester I am going to write a undergrad thesis about quantum computation, but my background is not from physics but from mathematics and computer engineering. In this talk http://www.youtube.com/watch?v=Rvn_3cCrl9c Andris Ambainis talks about how he got into the field of quantum computing...

Homework Statement q1]] Which of the following pairs of quantum gates commute? Select all that apply. (Gates A and B commute if and only if for any input applying A and then B gives the same results as applying B and then A. This is the same as saying that the unitary transformations commute.)...

Homework Statement Let a one-qubit system be in the state [SIZE="3"]\left|ψ\right\rangle = \frac{\sqrt{15}\left|0\right\rangle + i\left|1\right\rangle}{4}. If we perform a measurement to see whether the qubit is in the state [SIZE="3"]\left|x_{+}\right\rangle = \frac{\left|0\right\rangle +...

What is Quantum computation? And what is the scope in this field at present and in near future?

Hi all! this is my first hour on Physics forums! so my question is, which of the 3 named fields (cs, ee, phys) are more active in quantum computation/information? I am a double majored ee/phys and I've passed some cs courses. as far as I see, any quantum lab will contain researches from all...

Hams and Raedt gave a quantum computational algorithm to calculate the density of states of a spin system. Starting with an initial random state, they obtain the time evolution of the state. Later they take the inner product of the evolved state with the initial state. How does the inner...

hello,i had posted in this forum a question about linar algebra and quantum mechanics because i am studying quantum computation and information, i have the following book:"quantum computation and quantum information" by Michael A.Nielsen and Isaac L.Chuang. and i think it covers most topics of...

I have 2 questions about quantum computation that I find interesting. 1. I understand that because the qubits are in a superposition and therefore do not have defined values that they perform all the possible calculations at once therefore making it the most powerful and parallel processor...

I hope to pursue a research career in Quantum computation. Could anyone suggest some good universities in UK where active research is going on in this field?Any information is most welcome.

A qubit state can be represented geometrically by Bloch sphere. A Bloch sphere has infinite points and so a single qubit can represent infinite number of states. Qubit state is represented by, Ipsi> = cos(theta/2)I0> + exp(i(phi))sin(theta/2)I1> It is said in the Book on Quantum...

What graduate schools are the best if I want to pursue research in Quantum Computation? I know MIT has a good program and I am going to apply there but what other schools would you recommend? I would prefer to stay on this side of the Atlantic.

Hi, I'm new graduate student and I need to know what is the quantum computation about? My second question is the same as above for "particles physics". is anyone to help me? thanks

Hi guys. I’m a graduate student in physics. I’m interested in quantum computation. In what field of physics should I take up my further studies to get into this area? Any information is most welcome.Thanx in advance.

Hello, I'm a 4th year physics undergrad, so I'm about to decide what to do in my undergrad thesis. I'll do pure theoretical work, but I'd like to avoid copy-paste stuff and come up wityh something quite original, however I'm not sure what topic are available, maybe someone here will help...

Nice lectures describing the theory of Quantum Computation. I'm currently watching them. http://www.quiprocone.org/Protected/DD_lectures.htm

Hey all, I'm a beginner of the Quantum Computation and Quantum Information. For a long time, I feel very confuse about the question bellow. Could you do me a favor and show me the proof? Many thanks! Question: Show that any qubit can be expressed as psi=exp(iγ)[cos(θ/2)0+exp(iΦ)sin(θ/2)1]...

I'm doing a research paper on the deutsch problem in QC. My google inquiries have turned up numerous papers on solutions to the problem, but I am having difficulty finding a clear formulation of the problem itself. Can someone point me in the direction of this information?

So, as I have found out through my exhaustive search for a solid grad program, it is hard to find a close-knit group of quantum-computation-ers. After tossing a coin 3 times, I found the best place to look for anyone interested in the field is in this group rather than Computers or Engineering...

How to find a short-term Visiting Position in the area of Quantum Computation? I interesting to collaboration with other research groups. One of my results is Probabilistic Simulation of entangled states and Quantum Computation. I have the computer's program for simulation of Qubits in Pascal...
