Amazon Braket<\/a> enables customers to design and run quantum algorithms on a broad selection of quantum hardware through a unified interface. Today, we expand the hardware available on Braket with the general availability of IQM\u2019s latest quantum processing unit (QPU). The device, named Emerald, is a 54-qubit superconducting QPU providing customers higher fidelity gates and full square lattice connectivity.<\/p>\n

With the addition of IQM Emerald to Braket, customers can now access two IQM quantum processors: the 20-qubit Garnet and the new 54-qubit Emerald. Both devices are available through the Europe (Stockholm) Region, providing customers with greater choice in selecting the appropriate quantum hardware for their specific research needs and algorithm requirements.<\/p>\n

In this early phase of quantum computing, experimentation across a variety of available devices is crucial for developing quantum algorithms to eventually address complex problems across domains like finance, energy, pharmaceuticals, and logistics. Customers worldwide can now run experiments on IQM\u2019s most advanced quantum hardware, using on-demand access for designing and executing programs and priority access via Hybrid Jobs for running variational quantum algorithms, all with simple pay-as-you-go pricing. For workloads with latency or time-sensitive requirements, customers can reserve dedicated capacity on the Emerald QPU on a per-hour basis through Braket Direct.<\/p>\n

Advanced architecture for quantum research <\/p>\n

Emerald features IQM\u2019s Crystal 54 architecture, built using superconducting transmon qubits arranged in a square lattice and interconnected via tunable couplers. This high-connectivity configuration enables efficient mapping of quantum algorithms to the device topology. The square lattice design natively supports surface-code error correction, positioning it for future fault-tolerant quantum computing applications.<\/p>\n

The device supports arbitrary X and Y rotations as native single-qubit gates and uses the CZ gate as its native two-qubit operation. This gate set provides flexibility for implementing quantum algorithms while maintaining high fidelity operations. Early characterization data shows median single-qubit gate fidelity of 99.93% and median two-qubit gate fidelity of 99.5%. Up-to-date performance metrics can be found on Emerald\u2019s device details page in the Braket Console.<\/p>\n

Enhanced availability and accessibility <\/p>\n

Both IQM Emerald and Garnet are available 19 hours a day, enabling customers to run quantum workloads at their convenience regardless of time zone. enables continuous experimentation and development cycles for customers globally.<\/p>\n

Customers can access these EU-based QPUs in the Europe (Stockholm) Region, meaning customers can meet European data residency requirements and work with cutting-edge hybrid quantum-classical computing capabilities all in one environment.<\/p>\n

Getting Started with Emerald on Braket <\/p>\n

Braket provides customers a unified, easy-to-use programming interface to access quantum hardware. Customers can build, test, and run quantum programs on Emerald with the Braket SDK, or other popular programming frameworks, such as Qiskit, Pennylane, and NVIDIA CUDA-Q. To execute programs on Emerald, specify the Amazon Resource Name (ARN) in the device definition before running your circuit:<\/p>\n

device = AwsDevice(“arn:aws:braket:eu-north-1::device\/qpu\/iqm\/Emerald”) <\/p>\n

You can run a circuit with just a few lines of code as shown in the Bell State example that follows:<\/p>\n

from braket.aws import AwsDevice
\nfrom braket.circuits import Circuit<\/p>\n

device = AwsDevice(“arn:aws:braket:eu-north-1::device\/qpu\/iqm\/Emerald”)<\/p>\n

# run circuit
\nbell = Circuit().h(0).cnot(control=0, target=1)
\nresult = device.run(bell, shots=1000).result()
\n Exploring larger-scale quantum entanglement on Emerald <\/p>\n

The 54-qubit capacity of Emerald enables exploration of quantum algorithms that require substantial qubit resources. Building on the GHZ state experiments demonstrated with Garnet<\/a>, Emerald\u2019s expanded qubit count and high connectivity allow for even larger entangled states and more complex quantum circuits.<\/p>\n

Here\u2019s an example of preparing a 49-qubit GHZ state using Emerald\u2019s square lattice connectivity:<\/p>\n

from braket.aws import AwsDevice
\nfrom braket.circuits import Circuit<\/p>\n

device = AwsDevice(“arn:aws:braket:eu-north-1::device\/qpu\/iqm\/Emerald”)<\/p>\n

# Define a path through Emerald’s topology
\npath = [
\n 1, 2, 6, 12, 13, 14, 22, 30, 31, 39, 38, 46, 45,
\n 51, 50, 54, 53, 52, 48, 47, 41, 33, 32, 24, 23,
\n 15, 16, 8, 9, 3, 4, 5, 11, 10, 18, 17, 25, 26, 27,
\n 19, 20, 21, 29, 37, 36, 35, 34, 42, 43
\n]<\/p>\n

circuit = Circuit().h(path[0])
\nfor idx in range(len(path)-1):
\n q1 = path[idx]
\n q2 = path[idx+1]
\n circuit.cnot(q1, q2)<\/p>\n

task = device.run(circuit, shots=5000, disable_qubit_rewiring=True)<\/p>\n

Advanced quantum programming with dynamic circuits <\/p>\n

Emerald supports Amazon Braket\u2019s experimental dynamic circuits capability<\/a>, enabling quantum programs that measure qubits mid-circuit and apply quantum operations conditionally based on measurement results. This capability opens new possibilities for quantum error correction protocols, adaptive algorithms, and efficient qubit utilization through active reset.
The following example demonstrates qubit reuse through active reset using dynamic circuits on Emerald:<\/p>\n

from braket.aws import AwsDevice
\nfrom braket.circuits import Circuit
\nfrom braket.experimental_capabilities import EnableExperimentalCapability
\nfrom math import pi<\/p>\n

with EnableExperimentalCapability():
\n circuit = Circuit()
\n circuit.prx(1, pi, 0) # Flip qubit 1 to |1> state
\n circuit.measure_ff(1, feedback_key=0) # Mid-circuit measurement
\n circuit.cc_prx(1, pi, 0, feedback_key=0) # Conditional bit flip
\ncircuit = Circuit().add_verbatim_box(circuit)<\/p>\n

device = AwsDevice(“arn:aws:braket:eu-north-1::device\/qpu\/iqm\/Emerald”)<\/p>\n

result = device.run(circuit, shots=100).result()
\nprint(f”Measurement counts: {result.measurement_counts}”)
\n# Expected: predominantly “0” due to active reset<\/p>\n
