Quantum Algorithm In subject area: Computer Science A Quantum Algorithm refers to the use of quantum mechanical principles to carry out computational tasks or calculations. It includes algorithms such as Shor's algorithm, Grover's algorithm, Deutsch-Jozsa algorithm, Simon's algorithm, and Bernstein-...
A company such as Huawei has several options in how to deal with the problem of forward security of key exchange messages. It can immediately implement a promising post-quantum algorithm to replace Diffie- Hellman, but this introduces risks that the algorithm might be broken over the forthcoming ...

Then they are generalised to being quantum reversible, i.e., unitary (the classical networks we generalise are called feedforward, and have step-function activation functions). The quantum network can be trained efficiently using gradient descent on a cost function to perform quantum generalisations...
This model contains classical feed-forward neural network and the amplitude encoding QNN model as special cases. Moreover, it inherits the advantages and avoids the disadvantages of the amplitude encoding model. We give a quantum-classical hybrid procedure to implement the learning algorithm. The ...
A computation on a quantum computer works by preparing a superposition of computational states. A quantum circuit, prepared by the user, uses operations to generate entanglement, leading to interference between these different states, as governed by an algorithm. Many possible outcomes are canceled out...
We propose a quantum inverse iteration algorithm, which can be used to estimate ground state properties of a programmable quantum device. The method relies on the inverse power iteration technique, where the sequential application of the Hamiltonian inverse to an initial state prepares the approximate...
Inspired by Virginia Tech physicist Sophia Economou, the team started with an algorithm called ADAPT-VQE, which can efficiently prepare ground states. After some trial and error, they tweaked it so that it was scalable and able to create the ground state of a large system. They started by de...
we’ll run the algorithm on a simulator first to validate everything, and then we’ll run it on a real quantum machine when the code is ready. What I’m going to run here is a simple Q# function that returns a secret pattern of zeros and ones. Reme...
In the short term, PQC is more practical than QKD because it is algorithm-based and doesn’t require specialized hardware. As quantum technology evolves, security updates will likely involve incorporating PQC first because it is compatible with current infrastructure. In the ...
