Perceval Tech note: Introducing “shots” in a linear optic quantum computing framework

A “shot” represents the execution of a quantum circuit and the corresponding data collected by the hardware at the output during that single run. Given the probabilistic nature of the system, conducting multiple iterations of the system (obtaining many shots) is necessary to gather data for statistical analysis of the algorithm’s operation.

Budgeting with Qubits / Make the most of your photons

Are you looking for a way to do more complex computations with a limited photon budget but you find yourself not knowing your photon distribution at the end of your computation? Fear not, we have you covered! Keep reading to discover how to make the most of your photons with our new feature — pseudo photon number resolution (PPNR or pseudo PNR).

Exploring Ascella, the Single-Photon Quantum Computing Prototype

At Quandela have developed Ascella, a general-purpose single-photon-based quantum computing platform. Ascella is a quantum computer that uses a highly efficient quantum dot single photon source, which functions much like a miniature box that produces single photons on-demand which then go into its universal interferometer to perform the computation and subsequently are detected at the output for processing. 

Quandela Tech Report: Certified Quantum Random Numbers on a Small Optical Chip

What is randomness? And how can we generate it? Both questions — the first mathematical, the second technological — have profound implications in many of today’s industries and our everyday lives. Let’s explore the principles of randomness together, and some new results from Quandela that generate certifiable randomness according to the laws of quantum mechanics.

Entangled-photon generators for fault tolerant photonic quantum computers

This article is the summary of the scientific results in the new issue of the journal Nature Photonics ‘High-rate entanglement between a semiconductor spin and indistinguishable photons‘, which represents another “first” in the technological achievements of the quantum computing company Quandela, towards the development of photonic quantum computers.

Exploring Graph Problems with Single Photons and Linear Optics

Or, solving graph problems using a photonic quantum processor, with applications from chemistry to computer science, finance to artificial intelligence.

Perceval Tech Note: Strong Linear Optical Simulation (SLOS)

Perceval comes equipped with several backends for simulating your quantum algorithms. SLOS is a time-efficient way to get the output distribution of linear optical quantum circuits, with applications ranging from quantum machine learning to graph optimisation.

Photonics: The fast lane towards useful Quantum Machine Learning?

Photonic quantum computers are quickly establishing themselves as the leading platform for both near-term application (NISQ) and full-scale fault-tolerant quantum computing. They are scalable, natively compatible with quantum communications, and offer unique encoding schemes useful for quantum machine learning applications.

Cooking with Qubits / How to bake a Quantum Computer

How to build your own quantum processor from scratch! Whether you’re trying to impress a first date, cater for friends, or entrench a technological advantage against your geopolitical rivals, quantum computers are the perfect treat for any occasion.

What is a Quantum Computer?

Here we explain what quantum computers are and give a brief introduction to how they work. You don’t need a background in science to follow along, just a few minutes of spare time and a desire to learn.
