Does the Curry-Howard correspondence have a quantum-specific type system?
In Wikipedia we can read that
the Curry–Howard correspondence is a correspondence between formal proof calculi and type systems for models of computation. In particular, it splits into two ...

Does there exist a one-way quantum computer?
I'm wondering if we have managed to create a experimental version of a one-way computer and if so is there one available to "play with" as it is the case with circuit models which are ...

What type of tasks it is possible to solve on a quantum simulator?
In this article, the author claimed that researches from Harvard and MIT created 256 qubits quantum simulator. However, we are not talking about piece of software on a classical computer but actual ...

Modeling building blocks for quantum computation
If I would design library for quantum computation I would naively consider a sequences of entangled qudits with unit length as a building blocks. I.e., unit length elements from $$\mathbb{C}^{d_{1}}\...

What's the difference between Superconductor, Photonics, and Nuclear Magnetic Resonance implementation of the physical QC?
I'm a bit new to Quantum Computing and I wonder why organisations are using different physical architecture.
I realise that any physical implementation can be valid as long as it uses the fundamentals ...

How to simulate $H(\theta) = B(\sin\theta S_1^x +\cos\theta S_1^z +\sin\theta S_2^x +\cos\theta S_2^z)+aS_2^zI_z$ on IBM Qiskit
I am trying to simulate this Hamiltonian on IBM Qiskit, for varying values of $\theta$:
$H(\theta) = B(\sin\theta S_1^x +\cos\theta S_1^z +\sin\theta S_2^x +\cos\theta S_2^z)+aS_2^zI_z$
Where S is ...

What is the relation between the database made up of N elements and the index made up of a string length n in the query model?
I am working on a circuit model that contains a blackbox (query) and do not understand the relationship between what is in the black box and the way we get out the value of the element we index. The ...

Screening procedure in an iterative qubit coupled cluster (iQCC) ansatz
The paper Iterative Qubit Coupled Cluster approach with efficient screening of generators describes a new screening procedure for generators of the QCC ansatz.
How does one get from defining the ...

Can We Currently Import Quantum Datasets (Datasets Containing Quantum Data) Onto NISQ-era Quantum Computers?
I'm still investigating the TFQ whitepaper.
In one section of the paper, the authors say this with respect to Quantum Datasets
In general, [a quantum dataset] might come from a given black-box ...

What level of physics and math do I need to get into Quantum Computing (hardware)?
I already understand the abstractions of Quantum Computing (software), which includes qubits, interference, qubit entanglement, and circuits. However, despite being able to write Q# code that makes up ...
