As the field of quantum computing expands, so do the qubit modalities behind it. Which one ultimately dominates will depend on a combination of performance, capabilities, ease of implementation, and cost of ownership. While many of the early approaches have demonstrated small-scale logical qubits, they face technical barriers getting to high qubit counts, and in […]

The T centre and silicon are the ultimate quantum power-couple: combining telecom-band optical emission with established fabrication infrastructure. However, to truly unlock this pair’s potential, we need to ensure that T centre performance doesn’t degrade once integrated in devices.  A new paper by our partners at Simon Fraser University, “Laser-induced spectral diffusion and excited-state mixing […]

 The timeline to useful quantum computing just got shorter. Introducing SHYPS: the first QLDPC code family that can efficiently perform error-corrected quantum computation. The patent pending SHYPS codes use materially fewer qubits per logical qubit than traditional surface codes. Qubits — as quantum bits, the foundational building blocks for quantum computers are known — […]

What do the utility-scale quantum computers of the future look like? We believe that silicon spin-photon qubits are the path to utility-scale quantum applications and we are continuously innovating to extend their capabilities. We are excited to announce a new paper in collaboration with our partners at Simon Fraser University, “Electrically-triggered spin-photon devices in silicon”, […]

The development and implementation of any technology that opens new frontiers involves the transition from concept to prototype to minimum viable product, culminating in a scalable system with desired functionality. Early developments offer glimpses of the potential, while the broader achievement of scalable capacity unlocks true commercial value. These earlier stages of theory and possibility […]

Scalability is perhaps the biggest challenge facing quantum computing. Known technologies have fundamental limitations on how many qubits can fit in a single module, which poses the question of how to scale beyond the number of qubits that can be hosted by a single module. The ability to distribute entanglement answers this question. If a […]

Developing performant quantum systems of commercial utility will require hundreds to thousands of logical qubits. To achieve this capacity, quantum systems must be modular due to the upper limits of qubit capacity in any single monolithic machine. Photonic is focused on overcoming the challenge of entanglement distribution as the key to unlocking the potential of […]

Quantum computing is undergoing a period of rapid evolution. The era of noisy, intermediate scale quantum (NISQ) is coming to an end, and new systems demonstrating small-scale logical qubit architectures are attracting the interest of early adopters. We are entering the era of quantum error correction where the fidelity of qubits is improved by applying […]

Photonic is excited to announce the newly publicized results from our collaboration with research partners at Simon Fraser University and Dartmouth College. Our research, Optical transition parameters of the silicon T centre, now published in APS Physical Review Applied, delves deep into the physics of T centres, our chosen qubit technology. T centres are a […]

Today, we’re making three announcements at Photonic that we believe bring us a significant step closer to turning quantum computing’s potential into reality
