X-ALT-DESC;FMTTYPE=text/html:A quantum oracle separation between QMA(2) and QMA<br />Andrew Huang | UC Berkeley<br />We find a quantum oracle relative to which 𝖰𝖬𝖠≠𝖰𝖬𝖠(2). As a consequence, we resolve the no-disentanglers conjecture of Watrous: for every ϵ+δ&lt;1, any (ϵ,δ)-disentangler requires input size exponential in the number of output qubits. Our proof combines the unitarily invariant polynomial method of She and Yuen (ITCS '23) with a new construction based on the symmetric and antisymmetric subspace projectors, reducing the 𝖰𝖬𝖠 lower bound to the approximate degree of OR.&lt;br /&gt;Location<br /><ul><li>QNC 1201</li><li>Online on Zoom<ul><li>Meeting ID: 912 8146 6256 <br />Passcode: 494237</li></ul></li></ul>
