Welcome to the Quantum Network Explorer Platform, a state-of-the-art experimental quantum networking platform developed by QuTech, a collaboration founded by Technische Universiteit Delft and TNO, (“QNE,” “we,” or “us”). Hereby we explain under which terms You may use our online website https://www.quantum-network.com/ (“Website”) and software provided on or in connection with the Quantum Network Explorer (collectively the “Service(s)”). By accessing or using the Service, You acknowledge that You have read, understood, and agree to be bound by these Conditions of Use (“Conditions”) and to the collection and use of your personal data as set forth in the QNE Privacy Policy. These Conditions apply to all Website visitors, users, and others who access the Service (“User(s)” or “You”).

Please read these Conditions carefully and in full before using, registering or otherwise using the Website.

2. Use of the Service

QNE is a quantum networking platform designed and built by QuTech. It provides Users a variety of ways to run quantum network applications and examine the results. It provides a graphical interface to select and configure simulated quantum networks and applications and to visualize the quantum network, simulation steps, and results.

QNE is initiated by QuTech an advanced research center for quantum computing and quantum internet, resulting from a collaboration founded by Technische Universiteit Delft (“TUD”) and TNO. We want to provide Users access to various high-tech technologies to perform quantum computations and insights in principles of quantum networking and access to the community.

A. Eligibility

As QuTech is no legal entity, we must make clear towards You that the service is offered by TUD, also on behalf of its QuTech partner TNO. The Conditions will legally bind You towards TUD. By any form of use of the Service, whether it be by accessing, uploading or running code or downloading any results of processing, You agree to be bound by these Conditions of use. If You do not agree, You may not use the Service. Supplemental prevailing terms and conditions may apply to some Services, such as rules for a particular promotion, service or other activity, if applicable they will be disclosed to You.

B. Use of the Service

By using our Service You agree to apply adequate security policies and tools on your own networks and systems used to gain access to QNE, e.g. state-of-the-art scanners for viruses, to prevent unauthorised use of or access to QNE by third parties. You also agree to take precautions to avoid unnecessary loss of processor hours, e.g. by using the application configuration tools provided by QNE and to reasonably report any detected or perceived errors in our Service(s) (in for example the software, compilers, data communication) and system disruptions to QuTech (contact details below).

Subject to these Conditions, You are hereby granted a non-exclusive, limited, non-transferable, freely revocable license to use the Service for your personal, non-commercial use only and as permitted by the features of the Service. We reserve all rights not expressly granted herein in the Service and the QNE Content (as defined below). We reserve the right to terminate this license at any time for any reason.

The Services/computing resources (quantum networks and quantum network simulators) are shared by all Users. Requests for running an experiment may not be executed immediately but will be placed on a queue. Each backend imposes a limit on the computational resources used in our backend servers. In addition, a limit on the amount of time an experiment may run will be enforced by aborting running experiments that exceed this limit. Experiments has to be parameterized on the website or submitted via the API (either by using an ADK or SDK by initiating requests to the API directly). Limits apply to the number of experiments that can be stored in the result database.

To accept that the Service is offered by us on a reasonable efforts basis and that interruptions of the service may take place at any time, announced or not-announced. The Service may make use of external HPC-capacity which is limited by its very nature. Therefore, our staff, or staff of third party providers of computing and storage facilities utilized by us, shall have the following rights: (I) To assign priority to particular jobs without regard to the order of the queue; (II) To assign computing or storage resources to the uploaded jobs; (III) To relay certain jobs to external providers of computing or storage capacity without prior notification to You. Please note that it cannot be prevented that such providers gain access to experiments or code uploaded by You, unless explicitly agreed otherwise; (IV) To may decide not to execute or store a particular programmed application or to suspend or to delete an associated job or process in case it would exceed the available computer time of our server and/or third party computing or storage capacity utilized by us or systems of external providers that are used for QNE.

To manage the system usage and limit as much as possible the system downtime due to maintenance or any other unforeseen reasons. Normal downtime will be scheduled well in advance and will be announced on the Website.

C. QNE accounts
