D-Wave accounts are assigned Solver-Access Time (measured in seconds) based on your customer contract, subscription plan, or trial status. Usage is consumed whenever you execute problems on physical Quantum Processing Units (QPUs) or Leap Hybrid Solvers.

This article guides you through navigating the D-Wave Leap Portal to check your remaining time, analyze project consumption, and prevent solver quota depletion.

Overview

D-Wave accounts are assigned Solver-Access Time (measured in seconds) based on your customer contract, subscription plan, or trial status. Usage is consumed whenever you execute problems on physical Quantum Processing Units (QPUs) or Leap Hybrid Solvers.

This article guides you through navigating the D-Wave Leap Portal to check your remaining time, analyze project consumption, and prevent solver quota depletion.

Technical Prerequisites

To view allocation usage, ensure you have:

• An active account on D-Wave Leap Portal.

• Membership in at least one Leap Project (e.g., Trial, Academic, or Enterprise Plan).

How to Check Your Allocation Usage

1.Log in to D-Wave Leap:Sign in to the D-Wave Cloud platform.

1. Navigate to the D-Wave Leap Cloud Portal.

2. Log in using your account credentials or single sign-on (SSO) provider.

2.Select Your Active Project:Ensure you are reviewing the correct quota.

Solver-access time is tracked per project.

1. Click on your User Profile / Name in the top-right navigation menu.

2. Select Projects and choose the active project you want to check.

3.View Usage on the Dashboard:Review remaining QPU and hybrid solver time.

On the main Dashboard:

• Solver Access / Usage Gauge: Displays your total allocated solver time, elapsed usage for the current billing cycle, and remaining time balance.

• Renewal Date: Displays the exact date when your monthly solver time resets (for recurring plans).

• Solver Availability: Shows regional access status for QPUs and hybrid samplers mapped to your active project.

4.Inspect Submitted Problems:Analyze historical jobs and execution metrics.

Scroll down to the Problems section on the Dashboard:

1. View recent job submissions, execution status, and time consumed per job.

2. Click on an individual Problem ID to see granular timing metrics, including qpu_access_time or hybrid compute duration.

Understanding Solver Time Consumption

Different solvers consume your allocation quota at different rates based on hardware resources:

Solver Type	Consumption Metric	Description
QPU (Pure Quantum)	qpu_access_time	Tracks exact physical qubit programming, annealing, and readout time (measured in microseconds).
Leap Hybrid Solvers	charge_time	Tracks CPU/GPU classical pre-processing combined with QPU sampling time.
Simulators (e.g., neal)	Local CPU	Local CPU/GPU simulated annealers run entirely on your local machine and do not consume Leap solver allocation.

Checking Usage for Team & Project Administrators

If you hold a Project Administrator or Organization Administrator role in Leap Admin:

1. Click your Profile Avatar in the upper-right corner and select Leap Admin.

2. Navigate to the Projects tab to view organization-wide monthly usage metrics.

3. Click on a specific project to:

   • View member-by-member usage breakdowns.

   • Set per-user solver access limits to prevent individual members from depleting project quotas.

   • Export execution statistics for reporting.

Troubleshooting Quota Issues

Warning: SolverAccessError / Insufficient Quota

If your script fails with an access error, your active project has run out of solver-access time.

• Solution: Switch to a different project via the top-right menu, wait for your monthly renewal date, upgrade your plan on Leap, or test scripts locally using classical CPU samplers (dimod.SimulatedAnnealingSampler).
