<hr>
<blockquote>Superconductive systems are one of the few macroscopic
systems in which quantum mechanical behavior has been observed. In a
superconductor one can design, fabricate, and test circuits described
by using a wavefunction in which each current and voltage state may be
observed with some probability amplitude. Interference of these
amplitudes and entanglement between physically separated circuits can
be observed in this system. These properties make superconductive
circuits ideal for application to quantum computation. Also, because
superconductive devices can be fabricated using techniques of
microelectronic processing, the resulting circuits are potentially
scalable to the level of integration required to implement complex
algorithms.</blockquote>
<blockquote><br></blockquote>
<blockquote>In this seminar, we will review recent research in
superconductive quantum computation. In particular, we will focus on
the problem of device fabrication and characterization in this
system.</blockquote>

<div align="center"><font size="+2"><b>Spectroscopy on Two Coupled
Flux Qubits</b></font></div>
<div align="center"><br></div>
<div align="center"><font size="+1"><i>by</i> Dr. Johannes Majer
(<i>Yale University</i>)</font></div>
<div align="center"><br></div>
<div align="center"><u>ABSTRACT</u></div>
<div><br></div>
<blockquote>We have performed spectroscopy measurements on two coupled
superconducting flux qubits. The qubits are coupled inductively, which
results in a $\sigma_z^1 \sigma_z^2$ interaction. By applying
microwave radiation, we observe resonances due to transitions from the
ground state to the first two excited states. From the position of
these resonances as a function of the magnetic field applied we
observe the coupling of the qubits. The coupling strength agrees well
with calculations of the mutual inductance.</blockquote>
