Alice & Bob, a global leader in fault-tolerant quantum computing, has announced Felis 1.0, a toolbox featuring the first-ever logical qubit emulator. This innovation enables companies to prepare for practical quantum computing by facilitating the transition from current noisy intermediate-scale quantum (NISQ) devices to fault-tolerant algorithms.
According to Théau Peronnin, CEO of Alice & Bob, many business leaders are unaware that their teams’ quantum algorithms will not work as-is on industry-grade quantum computers, and Felis addresses this critical educational gap. Built on top of Qiskit, the popular quantum computing framework, Felis allows users to execute logical quantum algorithms and workflows designed for useful quantum computers based on cat qubits.
This platform enables researchers to explore quantum error correction techniques with logical qubits, potentially leading to gains in hardware efficiency and reduced overhead. The integration of Felis with Classiq’s platform and synthesis engine will also allow developers to optimize their circuits for logical qubits and study their sensitivity to noise.
Preparing for Practical Quantum Computing with Logical Qubit Emulation
The advent of quantum computing has brought about a significant shift in the way we approach computational problems. However, the current state of quantum computing is still in its early stages, and many business leaders are yet to realize that the quantum algorithms their teams develop will not work as-is on an industry-grade quantum computer. This is because logical qubits, which are necessary for achieving reliability in quantum computers, introduce noticeable differences with respect to today’s quantum hardware.
To address this critical educational gap in the quantum ecosystem, Alice & Bob has announced Felis 1.0, a toolbox featuring the first-ever logical qubit emulator. Felis allows users to prepare for impactful quantum computing by facilitating the transition from NISQ (Noisy Intermediate-Scale Quantum) to fault-tolerant algorithms. This is crucial because quantum algorithm developers will need to recompile their algorithms and reduce the overhead introduced by error correction to a bare minimum.
The Need for Logical Qubit Emulation
Logical qubits are essential for achieving the level of reliability required in quantum computers. However, they also come with significant differences compared to today’s quantum hardware. For instance, logical qubits require error correction, which introduces additional overhead that can affect the performance of quantum algorithms. To truly understand how to adapt algorithms so they can run on logical qubits and optimize them for fault-tolerant hardware, developers need a platform that allows them to examine how future quantum computers will differ from today’s devices.
Felis addresses this need by providing a comprehensive platform for algorithm development and logical qubit experimentation. Built on top of Qiskit, the most popular quantum computing framework, Felis leverages the power of the Qiskit ecosystem while adding cat-qubit-specific capabilities. This enables the execution of logical quantum algorithms and workflows designed for useful quantum computers based on cat qubits.
Exploring Quantum Error Correction Techniques with Logical Qubits
One of the key features of Felis is its flexibility in allowing users to tune hardware parameters and error rates to model their algorithms on different expected hardware maturity, both short and long-term. This enables researchers to explore quantum error correction techniques with logical qubits based on the innovative cat qubit. By doing so, they can observe potential gains in hardware efficiency and overhead enabled by Alice & Bob’s platform.
Additionally, Felis has been updated to make it compatible with IBM Qiskit 1.2, allowing developers to leverage its latest improvements, including faster compilation and emulation. This integration enables researchers to bridge today’s quantum innovations with tomorrow’s fault-tolerant breakthroughs.
Integrating Felis with Classiq Platform
Felis’ logical qubit emulator is now also available as an execution backend on the Classiq platform. Using Classiq’s powerful synthesis engine, quantum algorithm developers can optimize their circuits for logical qubits and study their sensitivity to noise. This integration combines Alice & Bob’s Felis toolbox with Classiq’s platform and synthesis engine, allowing developers and researchers to explore the practical implications of logical qubits.
Future Developments in Logical Qubit Emulation
Alice & Bob has announced that Felis will shortly be equipped with a resource estimator for cat qubits. This feature projects the qubits and resources required for building large quantum circuits, which is essential because some quantum circuits are too large to emulate on current classical and quantum hardware alike. The resource estimator already exists as a standalone application and will soon be integrated into Felis.
With Felis Logical Emulator available on Alice & Bob’s GitHub or on the Classiq’s platform, researchers and developers can start exploring the possibilities of logical qubit emulation today.
