In short: If I have access to a real quantum computer, is there a possibility to control it using Q#? Before you downvote this into nirvana because "there's no quantum computer available yet...

defining function for toffoli gate: def toffoli(qc,i1,i2,i3): qc.h(i3) qc.cx(i2,i3) qc.tdg(i3) qc.cx(i1,i3) qc.t(i3) qc.cx(i2,i3) qc.tdg(i3) qc.cx(i1,i3) qc.t(i3) qc.tdg(i2) qc.cx(i1,i2) qc.h(i3) ...

In Qiskit there is the transpile() function (see documentation). My understanding of a transpiler is best described as a way of converting one set of gate operations to another set of gate operatio...

Hi all: Cirq offers a way to create a unitary gate from an array. I tried doing the same in Qiskit but have not been able to quite make it. Here is a sample code with what I could put together so f...

I have a use case in Q# where I have qubit register qs and need to apply the CNOT gate on every qubit except the first one, using the first one as control. Using a for loop I can do it as follows: ...

For my AI class, I have to make a quantum tic-tac-toe game using alpha-beta pruning. I'm thinking about the best way to represent a state of the board - my first intuition is to use a sort of neig...

What is the difference between a physical and a logical qubit? I hope someone can help me with this question, I can't figure out exactly what the difference is. Best, Dirma

This is my first Q# program and i'm following this getting started link.https://learn.microsoft.com/en-us/quantum/quantum-writeaquantumprogram?view=qsharp-preview Error is The name 'BellTest' ...

I read a while back that Quantum Computers can break most types of hashing and encryption in use today in a very short amount of time(I believe it was mere minutes). How is it possible? I've tried ...

I've read time and again, as I dig through all the available literature, that in quantum computing, the smallest unit of value--a qubit--must remain "secret" or unknown until such a time as it is m...

While we are waiting for our quantum computers, is it possible to write a software simulation of one? I suspect the answer is no, but hope the reasons why not will throw some light on the mystery. ...

I'm trying to use the IBM Q Experience API and I installed the library and wrote a quick test code. At first, it couldn't find the module. Then, I added the whole sys thing. Admittedly, I just copi...

The only places I know that you can play with quantum computing are the google quantum playground and the ibm's quantum experience. While the first one uses qscript and the second qasm languages (w...

I have a von Neumann equation which looks like: dr/dt = - i [H, r], where r and H are square matricies of complex numbers and I need to find r(t) using python script. Is there any standart instrum...

I'm looking for algorithms that take an arbitrary quantum state made up of a sum of weighted classical states made up of bits, like this: |0000>/2 - |0011>/2 + |0100>/2 - |0111>/2 an...

I have just read an article talking about quantum physics. One interesting thing is that in a Haskell programmer's view there are some similarities between these two fields. First of all, measurem...

I often see people say if you can do X in some language you can do Y in another language which is the Turing Complete argument. So You'll have often (usually in a snide comment) "sure you can do t ...

Should practical quantum computing become a reality, I am wondering if there are any public key cryptographic algorithms that are based on NP-complete problems, rather than integer factorizat...

In physics, its the ability for particles to exist in multiple/parallel dynamic states at a particular point in time. In computing, would it be the ability of a data bit to equal 1 or 0 at th...
