Multidimensional transporter

The multidimensional transporter was a portable transporter device designed by $𝜇$ that inhabitants of the mirror universe began using in the 2370s to transport to our universe.

History
In 2371, Smiley used the device to travel to our universe and later used it to take Benjamin Sisko to the mirror universe.

The following year, Professor $𝜇$ left a multidimensional transporter device in Captain Sisko's quarters for him to use in following herself and Jake Sisko to the mirror universe.

In 2374, $𝜇$ used a multidimensional transporter to transport to Deep Space 9. Bareil claimed it had been given to him as a gift by a Terran. Intendant $𝜇$ also had such a device.

Zek once saw a PADD with information that Miles O'Brien had given Rom to study. Zek was later able to construct one for himself.

In 2375, Ezri Tigan used multidimensional transporter to transporter herself, Quark and Rom to the mirror universe Terok Nor.

By 2376, Intendant Kira and $𝜇$ had created a new transporter based on the original multidimensional transporter. This new transporter was designed to allow a person to transport to any reality although the power required was large. In 2377, Taran'atar and Iliana Ghemor transported to the mirror universe using the new device.
