Quantum dots are at the heart of Quandela's groundbreaking single-photon technology. These tiny semiconductor structures, often called "artificial atoms," are the key to producing high- quality, on-demand single photons. How quantum dots work: - Electron confinement: Quantum dots trap electrons in a nanoscale space, creating discrete energy levels similar to those in atoms. - Excitation: A short laser pulse excites an electron to a higher energy state. - Relaxation and emission: As the electron returns to its ground state, it releases a single photon with precise properties. - Directed output: Advanced cavity designs ensure the photon is emitted in a specific direction for easy collection. Advantages of Quandela's quantum dot technology: - Deterministic emission: Quantum dots can produce single photons on-demand when and as they are needed. - High purity: Unlike other methods, the probability of emitting multiple photons at once is extremely low, ensuring true single-photon states. - Indistinguishability: Photons produced by the same quantum dot are nearly identical which is crucial for quantum interference effects. - Brightness: A high percentage of generated photons can be collected, boosting overall efficiency. - Scalability: The solid-state nature of quantum dots allows for miniaturization of the single-photon sources enabling integration of a large number of devices. By precisely controlling the quantum dot environment and leveraging the Purcell effect in specially designed optical cavities, Quandela achieves unparalleled performance in single- photon generation. This technology opens the door to practical, large-scale photonic quantum computing and other cutting-edge quantum applications. Quandela's innovative approach to creating ready-to-use single photon sources involves a precise and sophisticated fabrication process: - Quantum Dot Growth: We begin by growing semiconductor quantum dots using advanced epitaxial techniques. These nanoscale structures are carefully engineered to emit photons at specific wavelengths. - Micropillar Fabrication: A key innovation is our method of deterministically placing quantum dots at the center of microscopic pillars. These pillars, made from alternating layers of semiconductors, act as optical cavities that enhance photon emission and collection. - Cavity Optimization: The micropillar's dimensions and material composition are finely tuned to create a highly efficient optical cavity. This design leverages the Purcell effect to boost photon emission into a preferred direction. - Electrical Contacts: We integrate electrical contacts into the structure, allowing precise control over the quantum dot's emission properties through applied voltages. - Fiber Coupling: Finally, we permanently attach (or "pig-tail") an optical fiber to each high-performance micropillar device. This creates a robust, alignment-free interface between the quantum dot source and standard fiber optic systems. The result is a compact, efficient, and ready-to-use single photon source that can be easily integrated into quantum photonic systems or experiments. This unique fabrication process enables Quandela to produce high-performance single photon sources at scale, paving the way for practical quantum photonic technologies.

Exploring Ascella, the Single-Photon Quantum Computing Prototype Quandela announces the launch of Ascella, the first functional Photonic Quantum computer. This is a key milestone for Quandela. 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. At its core, Ascella is a unique piece of technology that uses light to perform complex calculations. Its hardware is made up of several key components. Firstly, there is the single-photon source which produces the photons on demand. This source emits photons into a fiber which then sends the photons on their journey through the system. The system contains a device called a demultiplexer, which is responsible for splitting the stream of photons into separate streams. So it feeds the chip 6 photons that arrive at the same time. Secondly there is the unitary matrix in the universal interferometer which determines the evolution of the photons and finally detectors (SNSPD) at the outputs. Ascella is available directly in the cloud.
