Algorithm Updates

Q-Alchemy updates its qTucker algorithm to now have four different modes. But more importantly, the performance has been improved by 50 times! Furthermore, new enterprise features are introduced, notably customizable workflows configurable by a web-based editor. Lastly, up to 20-qubit workflows are immediately available to enterprise customers.

Updates on Q-Alchemy

Our team has developed three new sub-algorithms of our (patent pending) qTucker technology:

  • iterative tucker-decomposition excels at low-entanglement data or medium- to high-approximation data encoding.
  • hierarchical tucker-decomposition excels at high-entanglement and low-approximation data encoding.
  • Swap-pivot decomposition is a pre-processor to densify highly sparse data to apply either iterative or hierarchical approaches.

For users who prefer not to interact with decision-making processes, an automatic decider is also available. When combined, these four methods form Q-Alchemy, which provides amplitude data encoding support to all users.

Performance up to 50 times

Most importantly, our team worked to make significant improvements to the qTucker method’s computation. The new implementation uses improved numerics as well as mathematical insights from qTucker to speed up computations and approximations. According to our CEO, Dr. Blank, his team, particularly Dr. Araujo, has worked hard to discover and make these new approaches available to our customers.

With the new performance boost, 12-qubit computations take 1 - 2 seconds, while 20-qubit computations take slightly longer but still within 10 seconds. “We even tested the method on low-entanglement 26-qubit data,” Dr. Araujo adds.

New toolkit and API design

But this isn’t everything! We completely revamped our API. With the launch of a new web portal, developers now have additional options for configuring workloads to use quantum data encoding. Users now have more options to configure the qTucker algorithms according to their needs.

A user interface (UI) workflow editor that can be customized for enterprise workflows is also available to certain customers. Since this data originates in enterprise databases and ultimately ends up in the quantum computer, we provide a platform that considers it from beginning to end. Soon, more details will be shared regarding this development.

More Qubits for the Enterprise Plan

Our business clients can now take advantage of data encoding workflows that support up to 20 qubits. Up from 16 qubits before, this increases performance while decreasing infrastructure requirements, allowing for overall computation to be accessible in seconds instead of minutes or hours.
