Correcting errors with an efficient use of qubits
Quandela’s innovative photonic architecture brings us to fault-tolerant quantum computing closer than ever Fault tolerance represents a critical milestone in quantum computing. No matter the architecture you explore, current quantum computers are noisy, and one of the most challenging goals of quantum technologies involves performing reliable and useful tasks despite the noise affecting them. During…
Photon recycling, a novel method that improves quantum information
By Samuel Horsch and Alexandra De Castro Photons, the tiny particles of light, are the natural carriers of information. Whatever architecture we choose to create a quantum computer, there is no escape: photons must be involved sooner or later. As photons journey through optical fibers and other optical components, each photon carries a risk of…
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…
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…
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.
