Schrodinger Cats: the quest to find the edge of the quantum world
Dec 9 to Dec 13 2024, Okinawa, Japan
The generation of macroscopic quantum superpositions of massive objects have fascinated scientists since Schrodinger but scientific developments now promise that such superpositions may become possible in the very near future.
This meeting will focus on the science of macroscopic quantum superpositions - or more commonly known as Schrodinger Cats. In the 1930s Erwin Schrodinger made a thought experiment to test the boundaries of quantum mechanics. He asked if it could be possible, not only in principle, but also in practice, to make a quantum superposition of a large-massive object (in his case a cat), in two very different positions. As far as we know - this should be possible - but extremely challenging experimentally. If one can even achieve this for nanometer (or larger), sized particles one opens the possibility of tackling many fundamental questions e.g. how does quantum interact with gravity, is there some other addition to quantum mechanics which prevents the formation of such large-massive quantum superpositions? Can such massive superpositions be used for ultrasensitive sensors.
This meeting will bring experimentalists and theorists together to discuss recent science (experiment and theory), towards generating such quantum superpositions.
This workshop is hosted by the Okinawa Institute of Science and Technology Graduate University, Japan supported by the EPSRC Project Levinet.

Code of Conduct
We are committed to making our workshops (workshop(s) organized by OIST, hereinafter “our workshop(s)”) an inclusive space for sharing ideas and knowledge. We will not tolerate disrespectful communication, discrimination, harassment, or bullying in any form. As such, all participants attending our workshops are required to comply with this Code of Conduct. To provide all participants the opportunity to benefit from our workshops, we at OIST are dedicated to a positive, safe and harassment-free experience. Harassment in any form is specifically prohibited.
What is Harassment?
Harassment involves continued antisocial or unreasonable actions that violate a reasonable person’s personal rights and/or dignity and cause mental suffering, and thus worsen the person’s environment or make him/her anxious about participation. Behavior that is acceptable to one person may not be acceptable to another, so we ask that you use discretion to be sure that respect is communicated. Harassment intended in a joking manner nevertheless constitutes unacceptable behavior. Speech that is not welcomed or that is personally offensive, whether it is based on gender, age, sexual orientation, mental or physical disability, ethnicity, national origin, religion etc. will not be tolerated.
If you are being harassed, notice that someone else is being harassed, or have any other concerns, please bring this to the immediate attention of the organizers. If you wish to report an issue concerning the organizers, you can contact the Conference and Workshop Section directly and submit a confidential report by sending an email to firstname.lastname@example.org or submitting a report through the webform. All complaints will be taken seriously and responded to by the Provost promptly. Confidentiality will be maintained to the extent that it does not compromise the rights of others. Individuals found in breach of this Code of Conduct will be dismissed from the workshop immediately. Retaliation for reporting harassment is also a violation of Code of Conduct, as is reporting an incident in bad faith.
