Amazon Braket introduces local device emulator for verbatim circuits - devamazonaws.blogspot.com

Today, Amazon Braket introduced a local device emulator that enables developers to test verbatim circuits with device-specific characteristics before running on quantum hardware. This feature accelerates development by providing early feedback on circuit compatibility and expected behavior under realistic noise conditions, helping customers validate their quantum programs and develop noise-aware algorithms without incurring hardware costs.

The local device emulator offers several key capabilities:

  • Validates circuit compatibility with target quantum devices, including qubit connectivity, native gate sets, and device topology constraints
  • Simulates quantum circuits with depolarizing channels applied to one-qubit and two-qubit gates based on device calibration data
  • Provides realistic predictions of program behavior on noisy hardware using local density matrix simulation
  • Supports both real-time and historical calibration data for device emulation

Braket users can instantiate device emulators directly from AWS quantum devices or from custom device properties using the Amazon Braket SDK. The emulator seamlessly integrates with existing workflows, allowing developers to catch compatibility issues early and efficiently iterate on their quantum algorithms before running them on actual quantum hardware.

For more information, visit the Amazon Braket developer guide, read the launch blog post, and explore our example notebook demonstrating the local device emulator.

Research and Engineering Studio on AWS Version 2024.08 now available - devamazonaws.blogspot.com

Today we’re excited to announce Research and Engineering Studio (RES) on AWS Version 2024.08. This release adds new features such as Amazon S3 bucket mountpoints for Linux, allows creation of custom user roles and permission profiles, and offers the ability to adjust the list of Amazon EC2 instances available to launch as virtual desktops. Amazon S3 mountpoints allow Linux desktops to access S3 buckets as a file system. Amazon S3 buckets are created using the AWS Console or AWS CLI and onboarded to RES by administrators using the S3 Buckets page in the web portal. You can mount buckets in either Read Only or Read/Write mode. Read/Write buckets have an optional setting to restrict data access by project, or both project and user. RES can also mount S3 buckets from other AWS accounts with the proper permissions. Custom permission profiles allow administrators to create unique permissions and assign them to users or groups. Start by modifying the default Project Member and Project Ow...
